What is Hexahue? (Definition)
Hexahue is an alphabet made of colored blocks created from squares arranged in a 2x3 rectangle. The idea was to create a writing system based on bright colors and limited to 9 HTML colors.
How to encrypt using Hexahue cipher?
Hexahue uses 9-color square patterns within a 2x3 rectangular grid.
Hexahue supports 38 characters: the 26 characters of the Latin alphabet (from A to Z), the 10 digits (from 0 to 9) as well as the comma ,, the period ., presented in the following table:

Hexahue additionally uses 2 blocks to represent spaces, either ▮ or ▯ (one all black and one all white).
Example: HEXAHUE is coded
The correspondence is 1 to 1: a letter/number always corresponds to a symbol (for letters, upper and lower case are not differentiated).
In his original description, the author indicated that the other punctuations (.,()[]{}!?%$-+/*) could be achieved by combining other black and white square patterns.
How to translate Hexahue cipher?
Hexahue decryption consists of the transcription of colored rectangles into plain letters or numbers according to the correspondence table above.
Example: is translated DCODE
How to recognize a Hexahue ciphertext?
Any message encrypted by Hexahue is in a rather colorful image format with a maximum of 9 distinct colors: red, green, blue, yellow, cyan, magenta, white, gray and black.
Each color is theoretically present at 100% brightness (except for gray).
The symbols are made up of combinations of 6 colored squares grouped into a rectangle 3 high by 2 wide.
The letters are coded with the 6 primary and secondary colors: red, green, blue, yellow, cyan, magenta and never have the same color twice.
The digits/figures are coded with 3 levels of gray: white, gray and black, with mandatory 2 squares of each shade.
The punctuation (the point . And the comma ,) is coded with only black and white (3 black squares and 3 white squares staggered)
The spaces are either all black or all white.
The prefix HEX refers to the fact that there are 6 colors, but can also refer to the hexadecimal code for denoting HTML colors.
The author calls hexasquare each of the 6 small squares making up a hexahue symbol.
