The one-bit Gray code is G 1 = (0,1). This can be thought of as built recursively as above from a zero-bit Gray code G 0 = ( Λ ) consisting of a single entry of zero length. This iterative process of generating G n+1 from G n makes the following properties of the standard reflecting code clear:
The Magnavox Odyssey 2 is equipped with an Intel 8244 (NTSC) or 8245 (PAL) custom IC, and uses a 4-bit RGBI color palette. [34] [35] Bits 0 to 2 define Grid color, bits 3 to 5 define Background color, bit 6 defines Grid luminance (0=dim/1=bright) and bit 7 is unused.

A gray card is a flat object of a neutral-gray color that derives from a flat reflectance spectrum. A typical example is the Kodak R-27 set, which contains one 8 in × 10 in (20 cm × 25 cm) card and one 4 in × 5 in (10 cm × 13 cm) card, each with an 18% reflectance across the visible spectrum , and a white reverse side with a 90% reflectance.
This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.
2-, 4-, 8-, 16- and 32-color standard graphic modes, EHB 64-color and HAM 4096-color enhanced modes; 2 to 64 color modes pick from a 4096-color master palette (4 bits for each of red, green, and blue), with 64 color mode constructed from 32 normally chosen colors plus a second set of 32 fixed at half the intensity of the first.
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. When writing text to the screen, a BIOS color attribute is used to designate the ...

A color wheel is a tool that provides a visual representation of the relationships between all possible hues. The primary colors are arranged around a circle at equal (120 degree) intervals. (Warning: Color wheels frequently depict "Painter's Colors" primary colors, which leads to a different set of hues than additive colors.)
