Daily Colour Games — Test Your Eye Online

The ability to perceive and distinguish colour is something most people assume they're good at. They're usually wrong.

Not dramatically wrong — most people can identify that two colours are different. But accurately matching a specific shade, reading the ratio of red to green in a mixed colour, or noticing the subtle warmth in what looks like a neutral grey: these are skills with real variation between people, and with real room for improvement.

Daily colour games are a low-stakes way to find out where your eye actually sits on that spectrum.

Palette — the precision one

Palette is the most technically demanding colour game in this list. You're shown a target colour and three RGB sliders — red, green, blue. Your job is to mix a match.

Scoring uses Delta-E, a perceptual distance metric based on how human vision actually processes colour. A Delta-E of zero is a perfect match. Single digits are excellent. The lower the number, the better.

In practice: you're not just trying to get close — you're trying to get close by the standard of human perception, not by pixel arithmetic. Two colours that look nearly identical on screen might have a Delta-E of 3. Two colours with similar RGB values might have a Delta-E of 20 because of how hue and luminosity interact.

One puzzle per day. No account. Score resets tomorrow.

Palette also has a levels mode with 300 puzzles of increasing difficulty — but the daily puzzle is the cleanest entry point.

Colourdle — the analytical one

Colourdle applies the Wordle structure to colours. You guess a hex code; the feedback tells you whether each channel (R, G, B) is too high or too low. It's more analytical than visual — you're doing arithmetic as much as looking at the screen.

This one rewards people who think in hex values — designers and developers will find it accessible. If you don't read colour codes regularly, the format can feel opaque at first. Worth trying either way.

The Hue Test

The X-Rite hue test isn't a daily game — there's no puzzle round, no returning tomorrow for a new one. You arrange a series of colour chips in gradient order, and your score reflects how accurately your eye perceives hue differences.

Worth doing once as a baseline. Most people discover a weaker area in one part of the spectrum, often blue-green or red-orange. Knowing this makes you better at any colour game involving those ranges.

Colour Quiz

Colour Quiz presents two similar colours and asks which is closer to a target. The simplest format here, which makes it accessible without being trivial. The colours are often close enough that you have to actually look — not just pick the obvious one.

Good as a warm-up before Palette, or as a quick test when you want colour challenge without commitment.

Can you train your eye?

Short answer: yes, within limits.

Colour perception has a genetic baseline. Some people have higher cone density in the fovea — this gives finer hue discrimination, and no amount of practice will fully close the gap from a typical baseline.

But most people operate well below their genetic ceiling. The limiting factor isn't biology — it's exposure. People who work with colour professionally (designers, painters, photographers, textile workers) consistently outperform the general population on hue tests, and the difference appears to be learned.

The practical implication: daily colour games don't directly train your eye in a clinical sense, but they build attention habits. You get better at looking deliberately rather than glancing. That transfer is real, even if indirect.

If you want to see visible improvement, play Palette daily for two weeks and track your Delta-E scores. Most people drop 3–5 points in the first week simply by learning to look at the target colour longer before reaching for the sliders.
