How this Color Guesser works
- Read: you get a color name prompt.
- Pick: set hue, saturation, and lightness on the wheel.
- Reveal: see your pick vs the target and get a score.
Daily (UTC), Opposite, and Infinite
Daily is the same 5 prompts for everyone worldwide on that UTC date. Opposite is a complementary-hue twist. Infinite lets you practice as much as you want.
Scoring (ΔE-like, perceptual)
We score closeness using an OKLab-based distance (ΔE-like). That means two colors that look similar to humans score better than two colors that are numerically close in RGB but perceptually different.
Tips
- First nail hue (red vs orange vs pink), then adjust saturation, then lightness.
- Keep brightness consistent if you're tracking improvement.

Entertainment only — not a medical vision test. Screen calibration, night mode, and room lighting affect results.
FAQ
- What is Color Guesser?
- Color Guesser is a daily color puzzle: you see a color name, then use a color wheel to pick what you think it looks like. Reveal shows how close you were and scores up to 100 points per round.
- Is this a real color vision test?
- No. This is for entertainment and casual practice only — not a medical or professional vision test. Screens, brightness, and lighting can change results.
- Why does it say Daily (UTC)?
- Daily resets at UTC midnight so everyone worldwide gets the same 5 prompts for that date.
- What does “Opposite” mean?
- Opposite uses a simple wheel rule: it targets the complementary hue (about 180° around the color wheel) while keeping the same saturation and lightness profile. It’s a different kind of intuition challenge.
- How is scoring calculated?
- We score similarity using an OKLab-based distance (ΔE-like). Smaller perceptual differences earn higher points.
