What this trains, exactly
In MECCHA CHAMELEON, a Hider's round has two halves: choosing a spot the room can plausibly contain, then painting a white body to match it under time pressure. This trainer rebuilds both — every room is furnished with the community-measured center values of real surfaces from that map, you click to claim a spot, and the verdict judges your paint against the exact surface you stand on. It uses ΔE (CIELAB), the same perceptual color distance our color code library documents: under 2 is indistinguishable, under 5 blends at a glance, over 10 gets you found.
Fair-play notes
Use this browser drill to practice the color judgment that matters in real matches: hue, brightness, saturation, and whether the surface context makes the disguise believable. Colors are community-measured center values; live lighting shifts them, which is exactly why training your eye matters. For current game availability, use the Steam information page.
