Simply read the word and click the corresponding colour at the bottom of the screen. Difficulty rapidly increases with each correct answer.
Colour Drop is based on the Stroop Effect, where incongruence causes a delay in processing. Because the colour of the word doesn't match the word's text, the player will experience a delay in processing when asked to read the word.
