About this app
ColourQ: Colour Clash is a colour perception game that challenges you to match a target colour as accurately as possible using an HSV palette. HOW TO PLAY Each game has 10 rounds. A target colour is shown — drag the HSV sliders to mix your closest match, then hit Confirm before the timer runs out. The more precise you are, the higher your score. Accuracy is measured using CIELAB ΔE, the same standard colour science uses to quantify differences the human eye actually perceives. Every fraction of a percent counts. FEATURES • 10 rounds per game with a countdown timer • HSV palette — adjust hue, saturation, and brightness freely • Precision scoring based on human colour perception (CIELAB ΔE) • Game Center leaderboard — compete globally for the best average accuracy • Sound and haptic feedback (toggleable in Settings) • 9 languages: English, German, Spanish, Italian, Japanese, Traditional Chinese, Portuguese, French, Korean CHALLENGE YOURSELF Can you consistently score above 90%?
