In some uses, hexadecimal color codes are specified with notation using a leading number sign (#). [1] [2] A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified.
The original specification only had 8 colors, and just gave them names. The SGR parameters 30–37 selected the foreground color, while 40–47 selected the background. Quite a few terminals implemented "bold" (SGR code 1) as a brighter color rather than a different font, thus providing 8 additional foreground colors.
The Allegro library supported in the (legacy) version 4, an emulated 12-bit color mode example code ("ex12bit.c"), using 8-bit indexed color in VGA/SVGA. It used two pixels for each emulated pixel, paired horizontally, and a specifically adapted 256-color palette.

It is best to choose background colors that offer sufficient contrast in relation to text and blue links, which is also the color of references, both of which are very common in most articles. Use the WCAG link contrast checker to ensure that the chosen background color offers the recommended WCAG AA level of contrast against normal text ...
A BIOS Color Attribute is an 8 bit value where the low 4 bits represent the character color and the high 4 bits represent the background color. The name comes from the fact that these colors are used in BIOS interrupts , specifically INT 10h , the video interrupt.
