Hex Color Game

See a colour, guess its hex code: ten levels from greys to near-miss pairs, judged by CIEDE2000.

Level 1 of 10 · round 1 of 5

Greys

#rrggbb is three lights — red, green and blue — each a pair of hex digits, 00 for off and ff for full on. Equal digits make a grey, so #777777 is a middling one: the eye puts it at L* 50 of 100. Everything else in this game is a walk away from a grey.
