Guess the Color: Flag Quiz

How well do you really know the colors of the world's flags? Each round shows a flag with one part waiting for its color. Mix that color yourself with three sliders – hue, saturation and brightness – and lock it in. Then see your color next to the real one, painted on the flag. HOW IT WORKS • One color per round, 5 rounds per game • Every round is scored out of 10 with CIEDE2000, the color-difference formula used in color science: the closer your color, the higher your score • After each round, see which slider was off and by how much • Your game score is the average of your 5 rounds FLAGS FROM ALL OVER THE WORLD • 180+ national flags • 7 modes: Mixed, Arab World (all 22 Arab countries), Asia, Europe, Africa, Americas and Oceania • A Daily Challenge: the same 5 flags for every player, every day TRACK YOUR PROGRESS • Personal bests for every mode • Daily streaks • Share your result as an emoji grid and challenge your friends PLAY IN YOUR LANGUAGE Arabic, English, French and Spanish – switch anytime in Settings.
