Variants

Same dials, new rules

Twenty twists on the core game. Most are five rounds; some need a full room. Good warm-ups before jumping in.

Flags

A country's flag flashes, then vanishes — recreate its colors from memory. Powers the Color World Cup.

Chameleon

A chameleon covers part of a painting. Repaint its body from memory until it disappears.

Speed

1-second flash. 10 seconds to dial. Submit early for bonus points.

Memory Stack

Round 1 shows one color. Round 5 shows five in a row — remember them all.

Blind Sliders

No preview. Feel your way to the color from memory alone.

Gradient

The target is a 2-color gradient. Nail both endpoints.

Broken Slider

One slider's stuck on the wrong value. Compensate with the other two.

Match

A color match game. See the target, pick the swatch that matches it. Decoys close in every round.

Imposter

Spot the odd one out. Each round adds another swatch — and shrinks the gap.

Color Mixer

Mix red, green and blue light to match the target. Pure color-matching precision.

Hex Guess

See a color, type the hex code. Scored on how close you get, not just exact matches.

Spot the Difference

Two grids, one mismatched tile. Find where they disagree before the clock runs out.

Color Blind Test

Read the digit hidden in the dots. A free Ishihara-style color blind test.

Hue Sort

Arrange shuffled chips into a smooth gradient. A Farnsworth-Munsell-style hue test.

Color Sequence

Watch the colors light up, then repeat the growing sequence from memory.

Stroop Test

The word says one color but is printed in another. Tap the ink, not the word.

About this game

What is color memory?

Color memory is the short-term store your brain uses to hold a color you’ve just seen. It’s separate from your long-term memory of canonical colors like “fire-engine red” or “the blue of the sky”. The short-term store is fast, lossy, and limited — it can only hold a handful of distinct colors for a few seconds before they start to decay or merge with each other. The Color Memory Game tests that store directly: see a color, look away, recreate it with three sliders.

Most people don’t realize how unreliable color memory is until they try the test for the first time. The flash feels long. The color feels obvious. Then the sliders appear and they discover they can’t pin down whether it was teal or seafoam, whether it was as bright as it looked, or how saturated it really was. That’s the gap our game measures — and the gap that closes with practice.

Designers, photographers, painters, and color technicians spend years training a reliable color eye. The exercises they use are pretty simple — short flashes, side-by-side discrimination, naming the mix — done daily for months. We built this game as a structured way to do those drills: quick rounds, immediate feedback, and a scoring system based on real perceptual color science (CIEDE2000) so the numbers you see actually mean something.

If you’d like a deeper read, we have longer pieces on the science of color memory, why we score with CIEDE2000, and drills designers use to train a reliable color eye. Or jump straight into the full how-to-play guide for every game variant.

Color matching

Or play it as a color matching game

Color memory and color matching are related but distinct skills. A color guessing game asks you to recreate a color after it has disappeared. A color matching game keeps every color in front of you and asks how small a difference between them you can detect. Most players are stronger at one than the other, and the only way to find out which is to try both.

The Match variant is the strict color matching game: a target swatch and a grid of candidates, exactly one of which matches. The rest are decoys, and they close in every round. The Hue Sort variant is the Farnsworth-Munsell-style hue test: four to eight chips between two locked ends, drag the shuffled middle into a smooth sequence — untimed, so it measures your eye rather than your reflexes. The Imposter variant is the spot-the-difference cousin: no target shown, find the swatch that does not fit the rest. All three are free, all three run in the browser, all three are built for adults who want a real color-discrimination workout rather than a five-minute time-killer.

FAQ

Questions, answered

What is the Color Memory Game?+

The Color Memory Game is a free online color game that tests how well your eyes remember color. A target color flashes for a few seconds, then you recreate it from memory with hue, saturation, and brightness sliders — five rounds, scored out of 50. It also plays as a color matching game: the Match and Hue Sort variants keep every color on screen and test how small a difference you can spot.

How do you play this color guessing game?+

Click Play Solo to start. A color fills the screen for four seconds in Easy mode (or 2.5 seconds in Hard). When it disappears, drag the hue, saturation, and brightness sliders to match what you just saw. Submit your guess and see your score. After five rounds you get a final total out of 50.

What's the difference between Easy and Hard mode?+

Easy mode shows a Ready–Set–Go countdown on a black background, then reveals the target for a full four seconds. Hard mode flashes three decoy colors on the Ready, Set, and Go words, and only gives you 2.5 seconds on the real target — so you have to lock on fast while the decoys try to scramble your memory.

How is the color memory game scored?+

Scoring uses real color science, not raw slider math. Both colors are converted to CIELAB and compared with CIEDE2000, the industry standard for perceptual color difference. That distance becomes a 0–10 score on a sigmoid curve, with a recovery bonus for nailing the hue and a penalty for missing it on vivid colors. Getting the right color family is what counts most.

Can I play the color memory game with friends?+

Yes. Click Create room & invite friends to get a shareable link. Everyone who joins with a nickname plays the same rounds at the same time and sees a leaderboard at the end. You can rematch the same group in any of the eighteen room game modes without re-inviting anyone.

Does the game work on mobile?+

Yes. On phones the color fills the whole screen with vertical sliders on the left for one-handed play. On desktop the game plays in a centered card. It's a browser game — no app install, no signup.

Is the Color Memory Game free?+

Completely free. No signup, no paywall, no purchases. Just pick Easy, Hard, or a multiplayer room and start playing.

Can this color guessing game train my color perception?+

Regular play helps you notice subtle differences in hue, saturation, and brightness — the same way ear training sharpens pitch. Designers, photographers, and artists often use color memory drills to develop a reliable eye for color.
