Colors: Brain Reflex Game

It says "Red" but it's painted blue. Your brain hesitates for half a second. That half second is all you get.

You read "Green" but the word is painted orange. And the background is purple. Your brain stalls, and the clock doesn't wait.

Colors is a reaction game built on the Stroop effect, the same phenomenon psychologists have been studying for nearly a century: reading a word is automatic, naming the color it's printed in is not. When the two disagree, your attention has to pick a side.

HOW IT WORKS

The screen background changes color every round. Tap the word that names that background color, ignoring the color the word itself is printed in. Sounds easy. It isn't.

• You start with 7 seconds and the clock never stops
• Every correct tap gives time back, but the bonus shrinks as you go
• Every mistake costs you a full second
• At 10 correct answers a fourth option appears, and another at 20

No levels, no loading screens. A run lasts exactly as long as you do.
