Gradients RGB
Test your Color IQ in 60 seconds, then train your eye daily
Take the 60-second Color IQ test, then match colors by eye. Daily challenges, duels you send by link, and a mode that pulls colors out of your own photos. Works offline, no account.
Hi Product Hunt 👋
Most color-guessing games tell you "close" or "not close". I wanted an actual number, so I built one that measures it.
You see a color, you rebuild it by eye with red, green and blue dials, and it scores you with CIEDE2000, the same color-difference formula used to calibrate displays. It opens with a 60-second Color IQ test: a score out of 1000 plus how your eye leans on each channel. Mine: [your score and lean].
After that there's a daily challenge (the same three colors for everyone, one try), eight short drills, duels you send as a link (your friend gets the exact same colors, no account needed), and a photo mode where you match a color from the real world.
It's free, with no account and no third-party ads. Pro is $2.99/month and only removes the short breaks between training rounds. Code PRODUCTHUNT gives a month of Pro free.
I'm a solo developer. The most useful thing you can tell me is your Color IQ and which mode felt unfair.
