What we make

We create short, free games that explore color matching, visual memory, attention, color names and the boundaries between familiar hues. Most games take only a minute or two, work with a mouse or touchscreen, and generate new colors across repeated rounds.

Alongside the games, our editorial team publishes plain-language articles about color in everyday life: why clothing changes in sunlight, why a phone camera can turn purple flowers blue, how warm lamps alter a room, and why remembered colors drift. You can browse all games or start with our latest articles.

Why the site exists

Color is often presented as a fixed value—a name, a paint chip or a HEX code. Real perception is more interesting. A color depends on the light reaching an object, the wavelengths the object reflects, the display reproducing it, nearby colors and the observer's visual system. Memory and language add another layer.

Our goal is to turn those ideas into experiences that are approachable without oversimplifying them. A game gives you something to notice; an article explains why it may have happened.

How we approach accuracy

Articles are written and reviewed by the Color Percept Editors. For factual and scientific topics, we favor primary standards, public institutions, peer-reviewed research and established technical references. Sources are listed at the end of each article so readers can examine the evidence themselves.

Interactive color examples are demonstrations rather than calibrated laboratory measurements. Screens differ in brightness, gamut, color profile and viewing angle, while room lighting changes their appearance. We label illustrative values where that distinction matters.

What the games cannot tell you

Scores reflect a particular device, environment and moment. They are not standardized clinical measurements and cannot diagnose color-vision deficiency, eye disease or any medical condition. Anyone concerned about their vision should consult a qualified eye-care professional.

Our editorial principles

  • Answer the specific question promised by the title.
  • Distinguish measured facts from demonstrations and interpretation.
  • Link to relevant sources and correct meaningful errors.
  • Avoid presenting entertainment scores as medical conclusions.
  • Keep games free to play without requiring an account.
