Gradients RGB: Color IQ Game

New: the 60-second Color IQ test tells you how your eye really reads color. Plus duels you send by link, and colors pulled straight out of your own photos.

What's your Color IQ?

Five colors, about a minute, one number. Most people are far worse at this than they expect, and finding out is the fun part.

Free to play. No account required. Works offline.

THE COLOR IQ TEST A rating from 0 to 1000, where you land against everyone else, and a map of how your own eye reads red, green and blue. It will tell you which channel you consistently overshoot. Retake it whenever you want; ordinary play keeps the rating moving in between.

MATCH BY EYE A color appears. You rebuild it by eye, using either HSB dials (hue, saturation, brightness) or raw RGB channels, whichever your eye thinks in. Solid colors on Easy, flowing three-stop gradients on Medium, five-stop radial gradients on Hard. Score out of 1000 with a full per-channel breakdown and the exact hex you landed on.

DAILY CHALLENGE Three fresh colors every day, the same for everyone on Earth. One attempt, no hints. Keep your streak alive for growing diamond rewards, up to 40 a day.

DUELS BY LINK Play a set of colors, then send the link. Your friend gets the exact same colors, whether or not they already have the app. No accounts, no matchmaking, and nobody has to be online at the same time. They play, they see both scores, they send one back.

MATCH THE WORLD Point the camera at a sunset, a wall, someone's jacket. The app measures the real color inside the frame and you rebuild it by eye. Infinite levels, made by the world.

BRAIN TRAINING, 8 DRILLS Memory, mental color mixing, and split-second discrimination:

• Memory: see it for 4 seconds, rebuild it blind
• Blitz: 20 rapid-fire "which is redder?" calls
• Survival: one miss ends the run, colors get harder every round
• Color IQ: the adaptive acuity rating, on its own
• Negative: set the exact opposite of the shown color
• Mix: blend two colors in your head
• Midpoint: fill the missing gradient stop
• 2-Back: recall the color from two steps ago

PERCEPTION PROFILE The app quietly learns how your eye reads each channel, where you run warm and where you run cool, and tells you exactly what to train next. No other color app personalizes like this.

REAL COLOR SCIENCE Accuracy is measured with CIEDE2000, the same color-difference formula used in professional calibration, and shown as a plain delta E next to every score. A perfect match really is perfect: targets sit on exactly the steps the sliders move in.

SHARE ANY RESULT Every result makes a card worth sending: your number, the target, your attempt, and how far apart they actually were.

Gradients Pro is optional. It removes the short promo breaks between training rounds and can be bought once or monthly, your choice. Diamonds, earned free or purchased, pay for hints.
