One such type of Gray code is the n-ary Gray code, also known as a non-Boolean Gray code. As the name implies, this type of Gray code uses non-Boolean values in its encodings. For example, a 3-ary Gray code would use the values 0,1,2. [31] The (n, k)-Gray code is the n-ary Gray code with k digits. [63]
State diagram of 4-bit system, Gray code traverses just over its edges: Changes value always just of one bit step by step. The picture and this template share the same colors.

This 4-bit RGBI schema is used in several platforms with variations, so the table given below is a simple reference for the palette richness, and not an actual implemented palette. For this reason, no numbers are assigned to each color, and color order is arbitrary. Note that "dark white" is a lighter gray than "bright black" in this example.
A Hamiltonian cycle on a tesseract with vertices labelled with a 4-bit cyclic Gray code. Every hypercube Q n with n > 1 has a Hamiltonian cycle, a cycle that visits each vertex exactly once. Additionally, a Hamiltonian path exists between two vertices u and v if and only if they have different colors in a 2-coloring of the graph.
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.

Examples of six-bit binary codes are: International Telegraph Alphabet No. 4 [4] Six-bit BCD (Binary Coded Decimal), used by early mainframe computers. Six-bit ASCII subset of the primitive seven-bit ASCII; Braille – Braille characters are represented using six dot positions, arranged in a rectangle. Each position may contain a raised dot or ...
