Wong is Nonachrom's accessibility palette. It replaces the default nine colors with a set chosen so that the cells stay distinguishable for the most common forms of color vision deficiency.
The colors are adapted from Bang Wong's color-blind-safe palette, published in Nature Methods in 2011 and shared for community use. Seven of the eight colors are used directly; two luminance anchors were added by Chromix Games LLC so all nine cells separate cleanly.
You can switch between the default Nonachrom palette and Wong any time from Settings.

Sudoku, in color. Nine colors fill the grid, none repeating in a row, column, or box — and a finished board reads like a small piece of art.
The 9×9 logic grid was invented by Howard Garns and first published in 1979, later named Sudoku. Chromix Games LLC credits Garns as the originator of the rule structure; the color adaptation — name, mark, palette, design, and software — is original to Chromix Games LLC, created by founder Stuart S. Barrantes.
