Chromatch vs Zeroki

A color shows up on screen with six color options underneath. You have about a second to compare them directly. After that the color fades and you're going off memory. How well you see color and how well you remember it, both at the same time. If you pick the exact color you get 100%. The longer your streak, the more each pick is worth. The first rounds are pretty forgiving but the color appears for less time, the options start looking almost identical, and picks that were fine before start ending your run. The scoring uses Delta E, same formula Pantone uses to compare colors. TWO MODES Classic. One life. You keep going until a pick is too far off. Rush. Timer starts at 20s. Good picks add time, bad picks eat it. How much time you get back depends on how accurate you were. There are 8 tiers, Bronze to Grandmaster. You also build a signature color from every color you've matched. No two players end up with the same one. PLAY WITH OTHERS Daily Challenge. Seven rounds, one shot, a fresh color set every day.
