Explore color through short exercises, playful games and a daily challenge. Learn color names, compare tones and build your own mix. THREE TRAINING PATHS, TWO GAMES • Spectrum Explorer helps you practice neighboring color families and the boundaries between them. • Tone Specialist develops your eye for differences in lightness, chroma and hue within a color family. • Color in Motion brings those skills into animated scenes with shapes and ducks that fly, swim and walk. • Flip & Match is a color-memory game with six board sizes, Easy through Extreme difficulty, varied color families and a seed in every completion summary. • Color Slice challenges you to slice fruit in one to three target colors. Try changing palettes, four difficulties and games lasting 1, 2 or 5 minutes. A DAILY CHALLENGE BUILT FOR VARIETY Build your Daily Mix from Spectrum, Tone and Motion exercises. Optionally add a one-minute Color Slice game, a Flip & Match game, or both. Shuffle training and games, or choose separately whether each game stays at the end. Select 10–100 training rounds, revisit recent runs and share challenge seeds with friends to try the same mix with newly arranged questions and objects. LEARN A NEW COLOR EVERY DAY Discover the Color of the Day, its family, digital values and closest CSS color. Browse and search the offline color atlas, then add the Color of the Day widget to your Home Screen or Lock Screen for a new name each day. MADE FOR COMFORTABLE PRACTICE • Training answers are untimed and include an “I cannot tell” option. • Color Slice offers stationary, untimed play with VoiceOver or Reduce Motion. • Adjustable session lengths and saved progress. • Display and environment reminders that stay informational. • VoiceOver, Dynamic Type and Reduce Motion support. • Ten interface languages. • Offline exercises, atlas and saved statistics. FREE TRAINING, OPTIONAL SUPPORT Every exercise, Daily Challenge, color guide and widget is free.
