Stroop Test - Challenge your brain

In psychology, the Stroop effect is a demonstration of interference in the reaction time of a task.

When the name of a color (e.g., "blue", "green", or "red") is printed in a color which is not denoted by the name (i.e., the word "red" printed in blue ink instead of red ink), naming the color of the word takes longer and is more prone to errors than when the color of the ink matches the name of the color.
