Each day opens with a target hue (or, in the last round, a two-stop gradient).
See it before you play it.
Straight from the App Store: the daily rounds, the sliders, and the palette your days leave behind.
Hueful is a calm color matching game. Read the day's color, then mix it yourself by eye: three rounds, scored on how close it looks, not how close the numbers are. Train your color eye in a minute a day.

Under a minute. Then it's done. The point isn't to grind, it's to look closely once.
Each day opens with a target hue (or, in the last round, a two-stop gradient).
Move the sliders until your guess settles. Trust your eye.
Get a perceptual ΔE score and add the color to your growing palette.
No timers, no streak-or-lose pressure, no confetti. Just a quiet moment of looking, and a palette that grows one color at a time.
Every day you finish leaves its color behind. Over weeks it becomes a record of how you saw.
How to test, train, and trust your color eye, and where Hueful fits in.
What makes a good color matching game, how the three daily rounds work, and what your ΔE score really means.
