Shadeo

About Shadeo

Shadeo is a quick colour perception test. Look at the background colour and click the box of the same colour before time runs out. More boxes appear as you go.

It's closely related to our Odd Hue Out mode.

Timing is the winning factor: the background flashes a colour, and you must click the box with that same colour as quickly as possible. More boxes appear as you go, and one mistake ends the game – you fail once and you're out. That makes it a sharp test of colour memory and speed, similar to our Odd Hue Out but with a one-strike rule.

How to Play Shadeo

1. Look at the background.
2. Click the matching box.
3. Keep going before time ends.
