How do colours change?
Colours change by combining different colours together and using a spinning technique.
When blue and red are spun together on a spinning wheel they produce the colour purple.
When the colours green and blue are spun together they produce the colour turquoise.
These colours are produced depending on the speed of the spinning wheel. If the wheel goes slow you will not be able to see the colours change but if it goes fast you will be able to see the changing colours.
