[{"data":1,"prerenderedAt":-1},["ShallowReactive",2],{"content-seo:colorDiscrimination":3},{"description":4,"seo":5,"faq":8},"Color Discrimination Test is a quick \"find the different color\" game. A grid fills with tiles of one color, and exactly one tile is a little lighter or darker than the others. Tap that tile before the timer runs out to move on to the next stage.\n\nThe rules are simple and the same for everyone. The first two stages use a 2×2 grid; every two stages the grid gains a row and a column until it reaches 7×7 (49 tiles) at stage 11. Every stage has its own 15-second timer, and the game ends the moment it hits zero. A wrong tap costs one of your 3 hearts while the clock keeps running. Your score is the number of stages you clear, and it goes on the ranking board.\n\nThe difficulty curve is concrete: the odd tile starts 14 points apart from the rest in HSL lightness, with a small saturation shift on top, and the gap narrows by one point every two stages until it bottoms out at 3 points from stage 23. The hue never changes—only how light and how vivid the tile is.\n\nBecause of that, this is a game, not a color vision exam. It does not test red-green or blue-yellow color blindness, and screen brightness, color profile, night mode, and blue-light filters all change what you see. If you want a screening for color vision deficiency, use the Color Blindness Test instead. When the run ends, send a challenge link and see who can spot the different color faster under the same rules.",{"ogTitle":6,"ogDescription":7},"Color Discrimination Test | Find the Different Color - Giggleus","One tile is a shade lighter or darker—find it in 15 seconds.

For a self-check, use the Color Blindness Test; for a diagnosis, see an eye doctor."]
