Color Graphics Adapter
Color palette
Despite varying bit depths in CGA’s graphics mode (see below), CGA processes colors in its palette in four bits, yielding 2^4 = 16 different colors. The four color bits are arranged according to the RGBI color model: The lower three bits represent red, green and blue color components; a fourth “intensifier” bit increases the brightness of all three red, green and blue components.

With an RGBI monitor
These four bits are passed on unmodified to the DE-9 connector at the back of the card, leaving all color processing to the RGBI monitor connected to it. With respect to the RGBI color model described above, the monitor would use approximately the following formula to process the digital four-bit color number to analogue voltages ranging from 0.0 to 1.0:
red = 2/3*(colorNumber & 4) + 1/3*(colorNumber & 8);
green = 2/3*(colorNumber & 2) + 1/3*(colorNumber & 8);
blue = 2/3*(colorNumber & 1) + 1/3*(colorNumber & 8);
Dark Yellow
6
#AAAA00
Color 6 is treated differently; when using the formula above, color 6 would become dark yellow, as seen to the left, but in order to achieve a more pleasing brown tone, special circuitry in most RGBI monitors, including the IBM 5153 color display, makes an exception for color 6 and changes its hue from dark yellow to brown by halving the analogue green signal’s amplitude:
if (colorNumber == 6) green = green / 2;
It is this “RGBI with tweaked brown” palette, shown in the complete palette to the right, that all later PC graphics standards such as EGA and VGA have retained for compatibility.
With a composite color monitor/television set
For the composite output, these four-bit color numbers are encoded by the CGA’s onboard hardware into an NTSC-compatible signal fed to the card’s RCA output jack. For cost reasons, this is not done using an RGB-to-YIQ converter as called for by the NTSC standard, but by a series of flip-flops and delay lines. Consequently, the hues seen are lacking in purity; notably, both cyan and yellow have a greenish tint, and color 6 again looks dark yellow instead of brown:

RGBI Monitor availability
When the CGA was introduced in 1981, IBM did not offer an RGBI monitor of their own. Instead, customers were supposed to use the RCA output with an RF modulator (that they obtained separately, from a third party) to connect the CGA to their television set. The IBM 5153 Personal Computer Color Display would not be introduced until 1983. Resulting from the lack of available RGBI monitors in 1981 and 1982, many users would use simpler RGB monitors (without provisions for the ‘intensifier’ bit), reducing the number of available colors to eight, and displaying both colors 6 and 14 as yellow. This is relevant insofar as if an application or game programmer used either one of these configurations, he will have expected color 6 to look yellow instead of brown.
Standard text modes
CGA offers four BIOS text (Alphanumeric according to IBM) modes:
4025 characters in up to 16 colors. Each character is a pattern of 88 dots. The effective screen resolution in this mode is 320200 pixels (a pixel aspect ratio of 1:1.2), though individual pixels cannot be addressed independently. The choice of patterns for any location is thus limited to one of the 256 available characters, the patterns for which are stored in a ROM chip on the card itself. The display font in text mode (the code page 437 character set) is therefore fixed and cannot be changed (although when using the original IBM CGA in an original IBM PC, it is possible to select one of two different fontsormal or thiny changing a jumper. Many clones didn’t offer this possibility). The card has sufficient video RAM for 8 different text pages in this mode.
BIOS Modes 0 & 1 select 40 column text modes. The difference between these two modes can only be seen on a composite monitor; mode 0 disables the color burst, making colors appear in grayscale. Mode 1 enables the color burst, allowing for color. Mode 0 and Mode 1 are functionally identical on RGB monitors and on later adapters that emulate CGA without supporting composite color output.
8025 characters in up to 16 colors. Each character is again an 88 dot pattern (the same character set is used as for 4025), in a pixel aspect ratio of 1:2.4. The effective screen resolution of this mode is 640200 pixels. Again, the pixels cannot be individually addressed. Since there are twice as many characters on the screen in this mode, the card has enough video RAM for just 4 different text pages.
BIOS Modes 2 & 3 select 80 column text modes. As with the 40-column text modes, Mode 2 disables the color burst in the composite signal and Mode 3 enables it.
In every text mode, each character has a background and a foreground color.g. red on yellow text for one character, white on black for the next, etc. While the same 4-bit nybble used for the foreground color would normally allow all 16 colors to be used for the background color, the most significant bit of the background nybble is also used to denote whether or not the character should blink (a hardware effect offered by CGA independent of the CPU). The blinking attribute effect is enabled by default, so disabling it is the only way to freely choose the latter 8 color indexes (8-15) for the background color.
Notably, the GW-BASIC and, later, Microsoft QBASIC (a lesser derivative of Microsoft QuickBASIC) programming language interpreters included with MS-DOS (which was the de-facto PC OS while the CGA was popular) supported all the text modes of the CGA with full color control, but did not provide a normal means through the BASIC language to switch the CGA from blink mode to 16-background-color mode, though it would be possible by directly programming the hardware registers using the OUT statement. In BASIC, foregound text color numbers 16-31 are the blinking versions of colors 0-15, respectively, but background colors 8-15 are identical to colors 0-7 respectively. (Since BASIC sets up the graphics adapter registers either itself or through the BIOS, modifying them directly with OUT may be inadvisable, as it may conflict with the management of the adapter done by BASIC and/or BIOS and may therefore produce unpredictable results.)
Standard graphics modes
CGA offers two commonly-used BIOS graphics (sometimes called All-Points Addressable by IBM) modes:
320200 pixels, as with the 4025 text mode. In the graphics mode, however, each pixel can be addressed independently. The tradeoff is that only 4 colors can be displayed at a time. Also, only one of the four colors can be freely chosen from the 16 CGA colorshere are only two official palettes for this mode:

Red, green, brown/yellow and background color (any of the 16 colors, black by default).
By setting the high-intensity bit, brighter versions of these modes can be accessed.
The 1:1.2 pixel aspect ratio needs to be taken into account when drawing large geometrical shapes on the screen.
BIOS Modes 4 & 5 set up the 320200 graphics modes. Similar to the text modes, Mode 4 enables the composite color burst bit, Mode 5 disables it. Unlike the text modes, disabling the composite color burst bit (which setting Mode 5 does) in 320200 affects the colors displayed on an RGB monitor with the IBM CGA card and true compatibles (see below.)
640200 pixels, as with the 8025 text mode. All pixels can be addressed independently. This mode is monochrome with a pixel aspect ratio of 1:2.4. By default the colors are black and bright white, but the foreground color can be changed to any other color of the CGA palette. This can be done at runtime without refreshing the screen. The background color cannot be changed from black on a true IBM CGA card.
BIOS Mode 6 sets up the 640200 graphics mode. This mode disables the composite color burst signal by default. The BIOS does not provide an option to turn the color burst on in 640200 mode, and the user must write directly to the mode control register to enable it.
In text mode, font bitmap data comes from the character ROM on the card, which is only available to the card itself. In graphics modes, text output by the BIOS uses two separate tables: The first half of the character set (128 characters) is supplied by a table in the BIOS ROM chip on the computer’s mainboard at F000:FA6E, and the second half is supplied by the location pointed to by interrupt 1F (0000:007C). The second half of the character set is ordinarily absent, and trying to display it will result in garbage or blank characters. The character data may be placed into memory manually by the user, or by a utility such as GRAFTABL.

A number of official and unofficial features exist that can be exploited to achieve special effects.
In 320200 graphics mode, the background color (which also affects the border color), which defaults to black on mode initialization, can be changed to any of the other 15 colors of the CGA palette. This allows for some variation, as well as flashing effects, as the background color can be changed without having to redraw the screen (i.e. without changing the contents of the video RAM.)
In 640200 graphics mode, the foreground color can be changed from its usual white to any of the other 15 colors. The background and border cannot be changed from black.
In text mode, the border color (displayed outside the regular display areanto the overscan area) can be changed from its usual black to any of the other 15 colors.
A third 320200 4-color palette is achieved by disabling the composite color burst bit while in graphics mode. This is what IBM BIOS Mode 5 does, as described above. This switches the current color palette to red, cyan, white and the background color. The intense versions of these colors can also be used and the background color may be changed, but the palette cannot be switched to official palettes 0 or 1 without enabling the composite color signal again. As such, it can only be seen on RGB monitors and will simply appear in grayscale on composite displays. This palette was often used by games because it looked more attractive than the cyan/magenta/white colors. Notably, it is not mentioned in the IBM Reference Guide, and some CGA clones may not support it.
Through precision timing, it is possible to switch to another palette while the screen being scanned (drawn), allowing the use of any one of the 6 palettes per scanline. The best example of this in use is the game California Games when run on a stock 4.77 MHz 8088. (Running it on a faster computer does not produce the effect, as the method the programmers used to switch palettes at predetermined locations is extremely sensitive to machine speed.) The same can be done with the background color, to create the river and road in Frogger. Another documented example of the technique is in Atarisoft’s port of Jungle Hunt to the PC.
Additional colors are often approximated using dithering, although the low resolution makes it very apparent. In particular, many Sierra games use palette 1 at low intensity and dark blue as the background colour. This gives it the three primary RGB colours to work with (as well as brown).
Some of these above tweaks can even be combined. Examples can be found in several games. Most software titles did not use these possibilities, but there were a few impressive exceptions.
160100 16 color mode
Technically, this mode is not a graphics mode, but a tweak of the 8025 text mode. The character cell height register is changed to display only 2 lines per character cell instead of the normal 8 lines. This quadruples the number of text rows displayed from 25 to 100. These “tightly squeezed” text characters are not full characters. The system only displayes their top two lines of pixels (8 each) before moving on to the next row.
Character 221.
221 with blue text and red background color.
221 with red text and blue background color.
Character 222.
Character 221 in the extended ASCII character set consists of a box occupying the entire left half of the character matrix. (Character 222 consists of a box occupying the entire right half.)
Because each character can be assigned different foreground and background colors, it can be colored (for example) blue on the left (foreground color) and bright red on the right (background color). This can be reversed by swapping the foreground and background colors.
A single big “pixel” in 160100 mode. This is the two top rows of half of character 221. Note the 8 constituent pixels and the overall 1:1.2 aspect ratio.
Using either character 221 or 222, each half of each truncated character cell can thus be treated as an individual pixelaking 160 horizontal pixels available per line. Thus, 160100 pixels at 16 colors, with an aspect ratio of 1:1.2, are possible.
Although a roundabout way of achieving 16 color graphics display, this works quite well and the mode is even mentioned (although not explained) in IBM’s official hardware documentation.
More detail can be achieved in this mode by using other characters, combining ASCII art with the aforesaid technique.
Because the CGA has 16384 bytes of graphics memory, not 16000, it is just as easy to set the number of lines in this mode to 102 instead of 100 for a resolution of 160102. This uses extra video memory that is normally unused. However, most games did not do this, perhaps out of fear it would only work on some monitors but not others.
The same text cell height reduction technique can also be used with the 4025 text mode. This only made sense when using ASCII art, because without it the resulting resolution would only have been 80100.
Special effects on composite color monitors
Using the NTSC TV-out instead of an RGBI monitor not only made for less attractive colors, as described above, but as is common with NTSC composite video, the separation between luminance and chrominance is far from perfect, yielding cross-color artifacts, or color “smearing”. This is especially a problem with 80-column text:
80-column text on RGB (left) vs. composite monitor (right)
It is for this reason that each of the text and graphics modes described above exists twice: once as the normal “color” version and once as a “monochrome” version; the “monochrome” version of each mode would turn off the NTSC color decoding in the viewing monitor completely, resulting in a black-and-white picture, but also no color bleeding, hence, a sharper picture. On RGBI monitors, the two versions of each mode are identical, with the exception of the 320×200 graphics mode, where the “monochrome” version produces the third palette, as described above.
A flaw turned into an advantage
However, programmers soon found out that this flaw could be turned into an asset, as distinct patterns of high-resolution dots would “smear” into consistent areas of solid colors, thus allowing the display of completely new colors. Since these new colors are the result of cross-color artifacting, they are often called artifact colors. Both the standard 320200 four-color and the 640200 color-on-black graphics modes could be used with this technique.
Internal operation
Direct colors are the normal 16 colors as described above under “The CGA color palette”.
Artifact colors are seen because the composite monitor’s NTSC chroma decoder misinterprets some of the luminance information as color, as stated before. By carefully placing pixels in appropriate patterns, the skilled programmer produces particular cross-color artifacts yielding the desired color; either from purely black-and-white pixels in 640200 mode, or resulting from a combination of direct and artifact colors in 320200 mode, as seen in these pictures.
320200 palette 1
320200 palette 2
640200
Thus, with the choice of 320200 vs. 640200 mode, the choice of palette (1 or 2) and the freely-selectable color 0 in 320200 modes (see above), plus the ability to set the foreground color in 640200 mode freely, each one of these parameters results in a different set of artifact colors, making for a total gamut of over a hundred colors, of which 16 can be displayed at the same time.
Availability and caveats
The 320200 variant of this technique (see above) is how the standard BIOS-supported graphics mode looks on a composite color monitor. The 640200 variant however requires modifying a bit (color burst disable) directly in the CGA’s hardware registers, as a result, it is usually referred to as a separate “mode”, often just as “the” composite color mode, since its more distinctive set of artifact colors led it to being more commonly used than the 320200 variant.
Being completely dependent on the NTSC encoding/decoding process, composite color artifacting is not available on an RGBI monitor, nor is it emulated by EGA, VGA or contemporary graphics adapters.
Using the same monitor at the same settings, direct colors are constant from card to card and host system to host system. Artifact colors, on the other hand, tend to drift in hue. (This is unrelated to the hue shift problem encountered in the terrestrial reception of NTSC broadcast signals.) For this reason, the original IBM PC and XT design provides a trimpot labeled “COLOR ADJUST” (on the mainboard, not on the CGA card itself) which modifies the phase difference between the ISA bus’ CLK and OSC signals that leaves direct colors constant while changing the hue of artifact colors. If the trimmer is not adjusted properly, the composite output may not produce any color at all.
Host systems that lack a “COLOR ADJUST” trimpot, such as the Tandy 1000′s internal video hardware, might produce erratic artifact colors and require hue adjustment on the composite color monitor. Later AT systems usually do not provide a proper OSC signal at all, rendering the composite color display completely unusable.
Resolution and usage
Composite artifacting, whether used intentionally or as an unwanted artifact, reduces the effective horizontal resolution to a minimum of 160 pixels, more for black-on-white or white-on-black text, without changing the vertical resolution. The resulting composite video display with “artifacted” colors was thus sometimes described as a 160×200/16 color “mode”, though technically it was a method, not a mode.
The low resolution of this composite color artifacting method led to it being used almost exclusively in games, with many of the more high-profile titles optionally, sometimes exclusively, offering graphics optimized for composite color monitors:

Bugs and errata
The higher bandwidth used by 80-column text mode results in random short horizontal lines appearing onscreen (known as “snow”) if a program writes directly to video memory, as the CPU has priority when accessing it. This can be avoided by only accessing the memory during the period of vertical or horizontal retrace. The “snow” problem does not occur on any other video adapter, or on most CGA clones.
Another peculiarity of 80-column text mode is that, on composite displays, the picture will be grayscale unless the border is set to a color other than black, white, or gray. Setting the border color to brown results in the normal 16 colors being displayed, while other values cause the colors to become tinted.
The video controller 6845′s row counter being only seven bits wide, display RAM in graphics modes is laid out in a 2:1 “interlace” pattern, first laying out the data for rows 0, 2, 4, etc., then the data for rows 1, 3, 5, etc., adding additional software overhead for display RAM manipulation. This is unrelated to the NTSC field interlace.
Competing adapters
CGA had two main competitors:
For business and word processing use, IBM launched its Monochrome Display Adapter (MDA) at the same time as CGA, which produced a higher resolution text display in 8025 mode, rendering each character in a box of 914 pixels, of which 711 were the character itself. This produced sharper and more clearly separated characters than the CGA’s 88 dots text character matrix allowed. Because of this, MDA was the preferred choice for business use. Also, IBM initially manufactured the MDA card as a printer port/MDA combo card. This meant that users wishing to connect printers to their original IBM PC would have to pay for the MDA card anyway (initially $335), while the CGA card (initially $300) could be left out to save money. While including the CGA card and connecting an existing TV set for use as a monitor allowed users to forgo the purchase of a monitor, this was not significantly cheaper than buying a monochrome monitor (initially $345) and leaving out the CGA card. Also, 80-column text was almost unusable on color composite displays, and the IBM model 5153 CGA color video display that was required to fully exploit the CGA card’s capabilities was even more expensive. Since a great many PCs were sold to businesses, the sharp, high-resolution monochrome text was more desirable for running applications.
In 1982, the non-IBM Hercules Graphics Card (HGC) was introduced, the first third-party video card to be made for the PC. In addition to an MDA-compatible text mode, it offered a monochrome graphics mode. With a resolution of 720348 pixels, it had a higher resolution than that produced by CGA. The Hercules’ combination of sharp monochrome text and graphics capabilities made it ideal for running software such as Lotus 123 that supported business graphics. Some games also had Hercules support.
Important to the gaming community, the IBM PCjr and the compatible Tandy 1000, released in 1984, featured an onboard “extended CGA” video hardware that extends the video RAM to 32k, thus allowing 16 colors at 320200 resolution and 4 colors at 640200 resolution (later Tandys also had a 640200 mode with 16 colors). Similar but less widely used was the Plantronics Colorplus.
In 1984, IBM also introduced the Professional Graphics Controller, a or its time very sophisticated high-end graphics solution intended for e.g. CAD applications. It was mostly backwards compatible with CGA. The PGC did not see widespread adoption due to its $4,000 price tag, and was discontinued in 1987.
Another extension in some CGA-compatible chipsets (including those in the Olivetti M24, AT&T 6300, the DEC VAXmate, and some Compaq and Toshiba portables) is a doubled vertical resolution. This gives a higher quality 816 text display and an additional 640400 graphics mode.
The CGA card was succeeded in the consumer space by IBM’s Enhanced Graphics Adapter (EGA) card, which supports most of CGA’s modes and adds an additional resolution (640350) as well as a software-selectable palette of 16 colors out of 64 in both text and graphics modes. Along with this move, the price of the older CGA card was lowered considerably; it became an attractive low-cost option and was soon adopted by the new PC cloning companies as well. Entry-level non-AT PCs with CGA graphics sold very well during the next few years, and consequently there were many games released for such systems, despite their limitations. CGA’s popularity started to wane after VGA became IBM’s high-level standard and EGA the entry-level standard in 1987. However, most software made up to 1990 supported it.
