We can find colours everywhere around us

In the animal world

On plants and flowers

In beautiful landscapes

Also our cities are full of colours

Just think for a few seconds how our world would look like without

colours

Our life in black and white would be very different

Dark gray peppers, white traffic lights, a gray sea instead of a blue one...

We will lose a lot of information and beauty

Now we know the importance and usefulness of color. Let´s now

learn more about them

How do we see colours?

Colours are captured by the eye and reach the brain via the optic nerve

In 1666 Isaac Newton discovered that when sunlight passes through a glass prism, it is decomposed in 7 colours. These are the 7

colours of the rainbow

Water raindrops work as a glass prism and break up the sunlight into a rainbow

Rainbow colors are 7 and always appear in the same order:

red, orange, yellow, green, blue, indigo, and violet

Newton´s experiment proved that the colour is LIGHT

Now let´s see how colours are arranged and classified

They are the colours that can be combined to make all the range of colours.
