Palette Lab turns color memory into play
Palette Lab combines quick color games with hands-on color tools, so color practice feels useful instead of abstract.
HSB color guessing becomes concrete
Instead of reading color theory in isolation, you rebuild a specific color from memory and see the exact difference.
Color tools stay practical
The palette extractor focuses on usable output for real projects: HEX, RGB, HSB, OKLCH, CSS variables, and clean JSON.
How Palette Lab trains your color eye
Palette Lab is built around short feedback loops: guess, compare, adjust, and reuse the colors you discover.
01
Start with a color memory round
Open Toon Tone, study the character prompt, and use hue, saturation, and brightness sliders to fill the missing color from memory.
- Watch brightness separately from hue
- Replay rounds to notice your common misses
02
Compare color formats
Every submitted color becomes a concrete comparison: your HEX value, the original HEX value, and a score based on RGB distance.
This is intentionally simple for the MVP, which keeps the game fast and understandable.
03
Turn practice into reusable palettes
When you see a photo, logo, screenshot, or artwork with useful colors, send it through the palette extractor and copy the output into your design system.
The extractor works locally in the browser, so private screenshots stay on your device.
