Streak 0 Best 0

Guess mode: read the colour swatch up top and tap the matching #hex code from the four options. A correct pick extends your streak; a miss resets it to zero.

Match mode: a target colour appears with its hex label. Drag the R, G, B sliders until your preview matches, then submit. Score each of five rounds on how close you get.

FAQ

How do you play Hex Guesser?
It has two modes. In Guess mode, a colour swatch appears and you tap which of four hex codes matches it; correct picks extend your streak. In Match mode, you see a target colour and drag the Red, Green, and Blue sliders to recreate it, scoring 0–100 on closeness across five rounds.
How is the Match score worked out?
The game measures the distance between your RGB guess and the target in colour space. A perfect match scores 100; the largest possible miss scores 0. Your five-round average is then checked against your best.
Is Hex Guesser free, and does it need an app?
Yes, it is free. Hex Guesser runs in any modern browser on Android or desktop with no app, no download, and no signup, and it works fully offline. Your best scores stay on your own device.
Hex Guesser is BestForAndroid's colour literacy trainer. In Guess mode you read a hex triplet and pick the right code from four distinct options, with a streak to keep going. In Match mode you flip it: given a target hex, you rebuild the colour with R/G/B sliders and score up to 100 for closeness. A few minutes of either mode sharpens how you read colour channels. Free to play on Android or desktop, with no app, no download, full offline support, and scores saved on your device.
