COLOURS
Primary colours are basic colours that cannot be obtained by mixing other colours of light.
Primary Colours of light are: Red, Blue and Green.
Secondary colours are formed by mixing primary colours.
Secondary colours are: Cyan, Yellow and Magenta.
We are able to see the colour of an object as it reflects that colour into our eyes.
For example when white light falls on a green object, the object absorbs all the other colours and reflects only green light.
When we shine red light on a green object, the object will appear black as the green object can only reflect green light therefore, when red light is shone onto a green object, it is not refected and so the object would appear black.
This tells us that in order to see the colour of the object, the light shone must have the same colour as the object, the colour is then reflected and seen by our eyes.
