Shade the duplicate colors until every surviving color appears once in its row and its column.
A red glow marks two shaded cells that are touching — that's the one thing you can never do. Tap Check anytime to see whether a color still repeats, two shaded cells touch, or the surviving cells have been split.
Solachrom is solved by telling colors apart. Take a look — can you tell all of these apart at a glance?
If any two look alike, turn on the colorblind-safe palette, or add a distinct number to every color. You can change these anytime in Settings.

Hitori, in color. Shade the duplicate colors until every surviving hue stands alone in its row and its column.
An independent color variant of Hitori, a puzzle popularized by the Japanese publisher Nikoli. Chromix Games LLC is not affiliated with or endorsed by Nikoli; the name, mark, palette, design, and software are original to Chromix Games LLC, created by founder Stuart S. Barrantes.
Wong is Solachrom’s accessibility palette. It replaces the default 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 Solachrom palette and Wong any time from Settings.
