CONGRATULATIONS, YOU FOUND A SECRET PAGE!

Colour is an amazing thing.

Your eyes can see a fantastic range of colours – go into a DIY shop or an art shop and just look at how many different coloured paints there are!

Colour Vision Deficiency

Most of us can distinguish between a million different colours! Some people – who we wrongly call ‘colour blind’ can’t see as many colours, but they can still see thousands. And very rare people can see colours that most of us can’t! One woman can see over 100 million colours!

Did You Know? The correct term for those who can’t see all colours is ‘colour vision deficiency’.

How many colours can we see?

Unbelievable Optical Illusion

How we see colours also depends on what we are looking at and how much light there is. Colours seem to change if they are on dark or light backgrounds.

Believe it or not, the two squares marked A and B in this picture are the same colour!

Heres The Proof!

... And because of a thing called ‘Colour Constancy’ our brains will sometimes make us see the colours we expect to see! For example – it can make you see red strawberries when they are actually grey!

YOUR MISSION, SHOULD YOU CHOOSE TO ACCEPT IT …

Walls of Colour

Get a piece of paper and draw a brick wall on it. Or print this handy graphic.

Your Task

Now pick three different colour paints.
Using these paints, try to make as many different colours as you can so that every brick is different. But even though they are all different they will look ‘right’ side by side because they’ve all been made from the same colours mixed together.

If you also use black and white paints to lighten and darken your mixes you can now create even more different colours.
