ColorBrain uses scientifically validated neuropsychological tests — the Stroop Test and Eriksen Flanker Task — to sharpen your attention, boost reaction speed, and strengthen cognitive control.

HOW IT WORKS ▸ Color Mode (Stroop Test): See a word, tap the color the text is written in — not the meaning. Red text spelling "BLUE"? Tap red. Easy to understand, hard to master. ▸ Direction Mode (Flanker Task): Tap the direction of the center arrow while ignoring the flanking distractors. Focus is everything.

WHY IT WORKS These are gold-standard tests used by neuroscientists worldwide. Regular practice builds selective attention, cognitive flexibility, and mental processing speed.
