Swatch is an exploration of color, whimsy, and what your eyes are really capable of. The human eye can distinguish millions of colors β but most of us use only a handful of words to describe them. Science shows that color discrimination is trainable: the more you practice identifying subtle differences, the more colors you can actually perceive. Your brain builds new pathways. Your vocabulary expands. The world genuinely looks richer. Any color in the world can be created by blending two other colors together. The question is β which two? Pick one color from each palette, blend them together, and see how close you land. A score from 0 to 100 tells you exactly how accurate your eye is β calculated using the same perceptual color science that paint manufacturers and display engineers rely on. The more you play, the more colors you master, and the sharper your eye becomes. An editorial team crafts fresh, culturally relevant palettes for you to master β each one built around a theme, with colors named to evoke a mood, a place, a moment. This isn't just flavor. Research shows that language shapes color perception: when you have a word for a color, you literally see it better. The names are how your brain holds onto what your eyes are learning. Simple enough that anyone can play. Deep enough that you'll never stop improving. --- HOW IT WORKS --- DAILY SWATCH A new color every day, the same for everyone worldwide. Three attempts. A global Game Center leaderboard. Build your streak. Come back tomorrow. SHUFFLE ALL Your entire color library in rotation. Two ways to play: Practice β a quiet space to study color. Play at your own pace, revisit colors as many times as you need, and build real familiarity. The game learns which colors challenge you and gently brings them back until they click. Play β a fast-paced challenge that tests how quickly and accurately you can read color. A health bar ticks down as you play β strong blends restore it, weak ones cost you. The better your eye gets, the longer you last. PALETTES Curated 8-color sets, each built around a theme and a story. Start with First Coat β your foundation palette β then expand your library as you grow. Multiple difficulty tiers control how subtle the distinctions become. --- THE SCIENCE --- Behind the scenes, a spaced repetition system tracks every color you encounter. Colors you struggle with return more often. Colors you've mastered fade into longer review cycles. Depending on your proficiency, you'll have between 5 and 50 colors in active rotation. As you master some, new ones cycle in. This isn't random practice. It's the same learning science behind language apps β applied to color perception. And the research is clear: color discrimination is trainable. Your eye gets sharper the more you play. Every time you play, you're building something. --- NO ADS.
