Determining perceived color differences is challenging. Typically, color differences are calculated using distance metrics from color coordinates, but these don't always align with human perception. This game uses a method to systematically capture these differences for improved automatic color difference detection. The approach involves showing participants color triples and asking them to choose which of two colors is closer to a reference color. To address the issue of numerous, tedious experiments, a game was developed where players unknowingly provide data on perceived color differences. The article also discusses the game's design and results.

Color values sorted by their distance to the first color based on the distance metrics L1, L2, CIEDE2000 and the proposed method (Custom).
