Hue Hunt
A hex colour guessing game. A mystery colour appears — pick the hex code that made it, or switch to type mode and guess the code yourself to see how sharp your eye really is.
Three difficulty levels crowd the decoys closer together, and typed guesses are scored on true perceptual closeness and drawn right next to the answer. Streaks and best scores save in your browser — nothing is uploaded.
How to play
A mystery colour fills the swatch. In Pick mode you choose which hex code produced it from a set of candidates. In Type mode there are no candidates at all — you type a hex code yourself, and your guess is drawn right beside the answer with a closeness score out of 100.
Three difficulties change how cruel the decoys are:
- Easy shows 3 options that sit well apart.
- Medium shows 4, noticeably closer together.
- Hard shows 6, packed so tightly that only a trained eye separates them.
Press a number key to choose that option, or N to jump to the next colour. Skip moves on but breaks your streak.
Reading a hex code
A hex code is three numbers written in base 16. In #RRGGBB the first pair is Red, the middle is Green and the last is Blue, and each runs from 00 (that light off) to FF (that light at full). So #FF0000 is pure red, #FFFF00 is red plus green — which the eye reads as yellow — and #FF8000 is full red with half green, which is orange. Once that clicks, guessing stops being luck.
How the score works
Typed guesses are scored on perceptual distance rather than raw numeric difference, so being wrong in a direction the eye barely registers costs you little, while a near-miss climbs fast. Your current streak, best streak and best accuracy carry over between visits.
FAQ
How do I get better at guessing hex codes?
Read the swatch channel by channel before you look at the options. Is there more red than blue? Is any channel near 00 or near FF? Pinning down two channels usually eliminates most of the decoys on its own.
Are my scores saved?
Yes, in your browser. Best streak and best accuracy persist across visits; nothing is uploaded and there is no account. Reset scores clears them.
What is the difference between Pick and Type mode?
Pick is multiple choice and tests recognition. Type gives you no options at all, so it tests whether you can genuinely name a colour from sight.
