The word says RED, the ink is blue. Trust the ink — 45 seconds.

This is the Stroop test, one of the most famous experiments in psychology. Your brain reads the word automatically, so choosing the ink color forces you to suppress an automatic response — the same 'inhibitory control' you use to stay focused when distractions pull at you.
