What is Color?
Color is a memory test built around one fact: humans are terrible at recalling colour from memory alone. A single shade fills the screen while a countdown runs. When it vanishes, you rebuild it from scratch using three sliders for hue, saturation and brightness. Five colours per run, scored out of ten each, and the game states openly that this is a test most people fail.
How to play Color
Choose a difficulty with the toggle. Easy gives you more time to study; Brutal is marked “not fun.”
Start a solo or daily run. The first colour appears with a countdown timer. When the screen goes blank, drag the three vertical strips along the left edge to recreate the colour from memory.
Press the target button to lock in your attempt. The game shows your result beside the original. Repeat this for five colours, then review your score out of 50.00.
The premise is rooted in perception science rather than puzzle design. You can distinguish thousands of colours when placed side by side but reproduce almost none from memory. Color demonstrates this in ninety seconds by showing your HSB values next to the real ones, making the failure measurable rather than subjective. After scoring, the game delivers a single dry line of commentary. A 5.99 gets called the gentleman's C of colour; a 1.76 is told it brought the wrong answer to the right question.
Reading the feedback
Your attempt appears directly above the original in a single card, making near misses hard to ignore. Both versions show their HSB values, so you can see exactly where the colours differ. The score is shown to two decimal places, with a one-line verdict below it.
Available modes
Solo lets you play five colours at your chosen difficulty as often as you like.
Daily uses the same five colours for every player worldwide. You get one attempt per day, and a countdown shows how long remains in the current cycle.
Live multiplayer lets you host a round and play at the same time as your friends.
Challenge link lets you send others a link to play the same five colours whenever they choose.
Strategy for higher scores
Name the colour out loud while the timer runs. Verbal encoding survives the blackout better than a raw visual impression, and the sliders are ordered hue first, so having the word already decided saves seconds for fine-tuning saturation.
Set hue before adjusting anything else. It is the one dimension where being wrong is unrecoverable, whereas a mix that is slightly too pale or too rich still scores decently.
Watch the dark end of the scale. Very dark and very desaturated colours read as almost identical when recalling them from memory, and both sliders sit near the bottom of their strip, so small handle movements swing the score dramatically.
Scoring system
Each of the five colours scores from 0 to 10, calculated to two decimal places, so 50.00 represents a perfect run. The leaderboards maintain separate rankings for Easy, Hard, Brutal and the daily challenge.
