Train focus, fight your reflex.
The Stroop effect is the gap between reading a word and naming its color. Color Match turns it into a 30, 60, or 120-second sprint: a colored color-name flashes, you tap the pad matching the ink, and ignore the meaning. Easy mode mostly matches; hard mode lies 80% of the time and gives you 1.2 seconds per question before it skips.
Number keys 1–6 map left-to-right to the visible color pads, so you can rip through rounds without leaving the keyboard. Best score persists per difficulty:duration combo in localStorage, so each setting keeps its own leaderboard.
