A short look, then a real recall task
The target color is visible for 3 seconds. After it hides, the player rebuilds the color from memory instead of copying from a visible swatch.
Recall the color from memory
Each round shows a target swatch for 3 seconds—then it disappears. Rebuild it using HSB sliders. Ten rounds per game, scored by how close you get (ΔE).

Memory mode guide
What Memory mode trains
Memory mode is not just another color picker. It separates looking, remembering, rebuilding, and reviewing into one repeatable loop.
HSB keeps the challenge visual
Hue, saturation, and brightness match the way people describe color: which color family, how intense, and how light or dark it feels.
Delta E makes the result explainable
After each guess, the game compares the selected RGB color to the original target color and turns the color distance into points.
The summary shows both colors
At the end of 10 rounds, the result card places each remembered target beside the player guess, so misses are visible instead of hidden behind a score.
How to play Memory mode
Memory games are still ten rounds. Memorize each target briefly, then recreate it without peeking—scored by how close your HSB pick is (ΔE).
- 1Memorize the target — the colored card stays visible for 3 seconds while the timer counts down.
- 2Recall and dial H, S, B — when the target hides, rebuild it from memory. The preview on the right updates as you drag the sliders.
- 3Submit your guess — you'll see ΔE feedback, points for the round, and both swatches side by side.
- 4Finish ten rounds — open the summary to compare every remembered target against your guesses.
- 5Practice Classic too — switch to Classic mode anytime from the header for rounds where the target stays visible.
Practice method
How to get better at color recall
Treat each round as three small decisions instead of one guess: color family, intensity, then brightness.
| Habit | Why it helps |
|---|---|
| Name the hue first | Think red, orange, green, blue, or violet before the target hides. |
| Store brightness separately | Ask whether the color feels pale, medium, or deep. That helps after the swatch disappears. |
| Adjust saturation before final brightness | A grayish color and a vivid color can share hue but score very differently. |
| Use the result card | Compare target and guess after every round. The fastest improvement comes from noticing the same miss pattern twice. |
Memory mode FAQ
Is Memory mode the same as Classic Flag Tone?
No. Classic keeps the flag context visible while you adjust a target band. Memory mode hides a single target swatch after a short countdown, so the skill is color recall rather than flag-context matching.
How many rounds are in Memory mode?
Memory mode uses 10 rounds. Each round has one target color, one guess, and one Delta E based score.
Can I peek at the target?
Yes. After the memorization phase, the hidden target panel can be pressed and held briefly as an assist. That makes the game friendlier without changing the core scoring method.
Is this a medical memory or color vision test?
No. Memory mode is a casual browser game and practice tool. It is not a diagnosis, medical test, or clinical color vision assessment.
