Color Memory Game
A color flashes for 3 seconds, then disappears. Recreate it from memory using hue, saturation, and brightness sliders. Scored by Delta E 2000 perceptual difference. Five rounds, 100 points max. This is harder than it sounds — most first-time players score 50–70.
Memorize a color for 3 seconds, then recreate it from memory. Five rounds, 100 points max.
How to play
- Click Start Game.
- A color appears for 3 seconds. Study it carefully — this is your only look.
- The color disappears. Adjust hue, saturation, and brightness sliders to recreate it from memory.
- Click Submit Guess when you are happy.
- The target is revealed, and you see how close you got. Repeat for 5 rounds.
Why this is harder than the color guesser
In the color guesser, you can compare your guess to the target in real-time. In the color memory game, you cannot — the target is gone. You have to encode the color into visual working memory, hold it while you manipulate three sliders, and reconstruct it from your mental representation. Research on visual working memory suggests that color information decays rapidly: most people can hold a rough approximation of a color for 3–5 seconds, but the accuracy drops significantly beyond that. That is why this game is scored the same way (Delta E 2000) but is much harder in practice.
This is also why the game is a legitimate skill test, not just a novelty. The ability to hold a color in working memory and reproduce it accurately is a real design skill — designers who can look at a brand color and then pick it in a color picker without referring back to the source are using exactly this skill. The game is a workout for that specific capability.
Tips for higher scores
- Before the color vanishes, consciously note its warmth/coolness — this anchors hue in memory.
- Note whether it looks "muted" or "vivid" — this anchors saturation.
- Note whether it looks "light" or "dark" — this anchors brightness.
- Say it out loud in your head ("warm, muted, medium") — verbal encoding improves short-term retention.
- If unsure, err toward the middle of the range — extremes are more likely to be wrong.
Use cases
- Design skill practice. Train the visual memory you need to reproduce colors from briefs and screenshots.
- Warm-up exercise. A quick game before design work primes your color perception.
- Perception research. Compare scores across people to see how color memory varies.
- Team building. A fast, fun game to play during breaks.
Frequently asked questions
How does the color memory game work?
Each round shows a color for 3 seconds, then hides it. You adjust hue, saturation, and brightness sliders from memory to recreate the color you saw. When you submit, the game reveals the target and scores you on Delta E 2000 perceptual difference. Five rounds, 100 points max. This is a genuinely challenging memory test — most people score 50-70 on their first play.
What is the difference between this and the color guesser?
In the color guesser, the target is visible the whole time, so you can compare your guess to the target continuously and fine-tune. In the color memory game, the target disappears after 3 seconds — you have to remember it and recreate it from memory. The color guesser tests perception; the color memory game tests perception plus short-term visual memory.
How long is the target shown?
3 seconds. Research on visual working memory suggests most people can hold an approximate color in mind for 3-5 seconds, but the accuracy degrades rapidly. 3 seconds is long enough to register the color, short enough that you cannot carefully study it. If you find it too hard, the timing can be adjusted — but for fairness across plays, it is fixed at 3 seconds.
What is Delta E 2000?
Delta E 2000 (ΔE00) is the CIE standard for perceptual color difference. It accounts for the human eye being more sensitive to some hue regions than others, so a ΔE of 3 in the blues feels like a ΔE of 3 in the yellows. A lower ΔE means a better memory. A ΔE under 2 is essentially imperceptible; under 5 is close; over 10 is clearly different.
How are the points calculated?
Each round awards up to 20 points based on Delta E. ΔE 0 → 20 points; ΔE 10 → 0 points; linear interpolation in between. So a perfect memory is 100/100 across 5 rounds. Most first-time players score 50-70, and experienced players can reach 85+. The color memory game is harder than the color guesser because you cannot iterate — you have to commit to your first recreation.
Why does the target disappear so fast?
Because that is the point of the game. If the target stayed visible, you could compare colors directly and the game would just be the color guesser. The 3-second window forces you to encode the color into working memory and reproduce it from that encoded representation — which is what makes this a genuinely fun memory challenge rather than a perception test.
