About Color Memory Game
Free · No signup · Browser-based
Color Memory Game is a free browser game that turns the science of color perception into a daily test of memory and intuition. We flash a color (or several), and you try to recreate it from memory using three sliders — hue, saturation, and value. There’s no signup, no account, no app to install, and the whole thing works on a phone, a tablet, or a laptop.
Why we built it
Color is something most people use every day without ever measuring it. Designers, painters, photographers, and artists spend years training their eyes to tell the difference between a warm grey and a cool one, or between two reds that look identical until you put them side by side. We wanted a quick, repeatable way for anyone to measure that skill — and to watch it improve.
The first version was built as a weekend experiment. After showing it to a few friends, the project grew into a full set of variants and a daily challenge that anyone in the world can play against the same target colors at the same time.
How the scoring works
Most color games score by checking individual RGB channels. We wanted something more honest, so we use CIEDE2000 — the perceptual color difference formula recommended by the International Commission on Illumination. CIEDE2000 measures how different two colors look to a human observer, not how different the underlying numbers are. Two greens with the same RGB distance can feel completely different to your eyes; CIEDE2000 reflects that.
On top of CIEDE2000 we add a small time bonus in the timed variants, so a quick, close guess beats a slow, near-perfect one. The Arena and Daily modes use the same scoring system across every player, which is what makes the leaderboard fair.
The variants
Solo is the classic mode: see the color, dial it back from memory. From there we built variants that strip away or add constraints — a one-second flash in Speed, no live preview in Blind Sliders, a single locked slider in Broken Slider, two-color targets in Gradient, sequence recall in Memory Stack, and an “odd one out” puzzle in Imposter. Multiplayer rooms add Sabotage (debuff your opponents) and Color Whispers (a chain of guesses that drift).
Every variant is built around the same idea — close the gap between what you remember and what was actually there.
Daily challenge & multiplayer
The Daily challenge uses a deterministic seed tied to the calendar date, so everyone who plays today plays the same five colors. Your score is comparable to anyone else’s — there’s no luck-of-the-draw advantage. Multiplayer rooms run live over Supabase Realtime: a host generates a code, friends join, and rounds resolve simultaneously.
Privacy & open feedback
We collect as little as possible. Leaderboard nicknames and scores are stored; nothing else. Read the privacy policy for the full breakdown, and please email us via the contact page if you spot a bug, want a new variant, or have a partnership idea.
