Can you remember a color perfectly? Prizma is the ultimate color memory game that trains your eye, sharpens your perception, and challenges you to reproduce exact shades from memory — using the same HSB model that designers and artists rely on every day. HOW IT WORKS A solid color floods your screen. You have 3 seconds to memorize it — hue, saturation, brightness. Then it disappears. Using three precision sliders (Hue, Saturation, Brightness), you recreate the color entirely from memory. Submit, and a split-reveal shows you how close you were. Score out of 1000: • 800–1000 → Excellent • 500–799 → Good • Below 500 → Keep practicing SCIENCE-BACKED COLOR TRAINING Prizma uses HSB (Hue-Saturation-Brightness) — the industry-standard color model used in design, photography, and fine art. Every round trains a different part of your visual cortex. Over time, your color perception improves measurably. GAME MODES Daily Challenge — One shared color for all players worldwide.
