Color Mix
A target colour on the left. Your mix on the right. Three sliders — red, green, blue. Drag them until your colour matches the target. Submit, score, new colour. How good is your eye?
What it is
Color Mix is a perceptual game about matching colours. The game shows a randomly-generated target colour. You have three sliders — one each for the red, green, and blue channels — and your job is to mix a colour that matches the target as closely as you can. When you submit, the game computes the perceptual distance between your colour and the target and converts it into a score from 0 to 100. A new target appears, and your average score across rounds is what you're really chasing.
How to play
- Look at the target swatch (left). Your current mix is on the right.
- Drag the three sliders — R, G, B — until your mix looks like the target.
- Submit. The game scores how close you got (0-100) and shows the actual RGB values of both colours.
- A new target appears. Your running average is the real score.
- Best average is saved in this browser, measured over the first 10 rounds of a game.
The trick
Most people can judge brightness well but struggle with hue and saturation. The trick is to solve the channels one at a time, not all together. First, get the overall brightness roughly right by moving all three sliders together. Then identify the dominant hue — is the target reddish, greenish, bluish? — and push that channel up. Finally, fine-tune the two minor channels, which control saturation and the subtle warm/cool cast. Trying to "see" the RGB values directly is much harder than reasoning about them as brightness, then hue, then saturation.
What this scored well on
- The skill is real and trainable. Color Mix scores improve noticeably with practice — your eye genuinely calibrates. The average score across a session is a clean, honest metric of perceptual skill.
- The scoring is perceptual, not naive. We weight the channels roughly by how sensitive human vision is to each (green most, blue least), so the score tracks how different the colours look, not just their raw numeric distance.
- It's genuinely useful. Designers, photographers, and anyone who works with colour will find this is a real warm-up exercise, not just a game.
What it gets wrong
Color Mix depends entirely on your display. A poorly-calibrated monitor, a phone in night-shift mode, or strong ambient light will all change what you see and therefore your scores. We can't fix this — the game is fundamentally about your eye plus your screen. If you're getting unexpectedly low scores, check whether your display has a colour filter enabled. Players with colour vision deficiency will also find certain target colours much harder; we didn't build an accessibility mode for this game, and we're honest that it's not equally playable for everyone.
Who it's for
Color Mix is for designers, illustrators, photographers, and anyone who wants to sharpen their colour perception. It's also a satisfying casual game for people who just like the feeling of "getting it exactly right" — the moment your mix swatch and the target become indistinguishable is quietly excellent.
