Round 1

Ready to remember?

You will have five seconds with the colour. Once it disappears, rebuild it from memory.

Round 1 is ready.

Perception becomes memory

The colour is easy. Keeping it is hard.

Every round shortens the study time and adds a stronger interruption. Your score measures the RGB distance between the vanished colour and the one you reconstructed.

Memorise a colour, wait for it to disappear, and rebuild it from RGB controls across five daily rounds.

Five daily memory rounds
Typical round
About 4–7 minutes
Cost
Free, with no download required

The rules

Study each colour during the viewing phase. Once it vanishes, reconstruct it with the RGB controls and submit to see the target and your remembered mix together.

What makes it different

Removing the reference separates colour memory from ordinary matching and shows how quickly a precise visual impression drifts.

How to play

Remember first. Mix second.

  1. 01
    Study one colour

    You get a few seconds. RGB values are never shown.

  2. 02
    Hold it through the gap

    The target disappears and later rounds add visual interference.

  3. 03
    Rebuild from memory

    Mix red, green and blue, then reveal both colours and their exact values.
