Wong is Tetrachrom's accessibility palette. It replaces the default four 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.
You can switch between the default Tetrachrom palette and Wong any time from Settings.

Color at speed. Four colors fill a 4×4 grid, none repeating in a row, column, or 2×2 block. Every board has exactly one answer, and every answer can be reasoned out — you will never have to guess. Chain completed lines in quick succession for bonus points.
An original Chromix design. The board, the four-color rule, the rotation, and the chain window are an original combination by Chromix Games LLC (2026), created by founder Stuart S. Barrantes.
