Round 1

Watch for the change.

You will see one colour, a short pause, then another. Choose the one thing that changed.

Round 1 is ready.

Memory, not matching

The reference disappears before you decide.

Early changes are obvious. Later ones are shorter, quieter and separated by a longer pause. Each answer reveals the two colours together and explains the exact dimension that moved.

About the game

How to play Second Sight

Remember two fleeting colours and identify exactly how the second changed across ten increasingly subtle daily rounds.

The rules

Study one colour, hold it through a blank interval, then study a second. Decide whether the second became lighter, darker, more vivid, more muted, redder, greener, yellower or bluer.

What makes it different

The colours never appear together until after the answer. Each round changes exactly one perceptual dimension, turning colour memory into clear, learnable feedback.

How to play

Spot what changed.

  1. 01
    See the first colour

    Take in its brightness, intensity and colour direction.

  2. 02
    Hold it through the pause

    The gap grows and viewing time shrinks as the daily challenge progresses.

  3. 03
    Name the one change

    The colours appear together only after you commit, with a plain-language explanation.

Useful language: vivid means more intense; muted means closer to grey.
