How the demo goes

Read the color, not the word.

  1. 1

    Look at the ink

    The word "GREEN" might be written in red: red is what counts.

  2. 2

    Answer at your own pace

    One 90-second timer for the whole demo, no limit per word. Click the color or use keys 1 to 4.

  3. 3

    Count your correct answers

    Your score is the number of correct colors out of ten.

Score guide

How to read your score.

The number of correct colors across ten words. The written word is a trap on purpose: that's the whole challenge.

  • 0–4 Try again The written word often wins at first.
  • 5–6 Sharp eye More than half the traps dodged.
  • 7–9 Super focused The written word barely fools you anymore.
  • 10 Flawless Not a single trap caught you.
