About Huekle — read a color and close the gap

Huekle trains the most fundamental color skill of all: holding a target shade in your mind and judging how far your guess sits from it along three axes at once — hue, lightness and saturation. That three-way estimate is exactly what you do when matching a paint chip to a wall, picking the swatch that reads true under shop lighting, or deciding whether a photo needs to go warmer or cooler.

You have five tries to land on the day's hidden color. After each guess, Huekle tells you whether you are too warm or cool, too light or dark, and too vivid or muted, so every attempt narrows the gap and teaches you to read those directions faster.

The feedback maps onto how we describe color in three dimensions. Learn warm and cool color temperature, or explore the full set of Learn about color guides.
