Fun facts
By mixing red, green and blue light we are able to make almost any other colours. Red, blue and green light is for that reason called primary colours. If you mix equal measures of each primary colour, you will get white or grey light.
The colours on a TV or a computer screen are made by mixing the primary colours red, green and blue.
If we mix red and blue light we get magenta (purple). Red and green will give yellow light. Green and blue gives cyan (light-blue). These are called secondary colours.
