What are primary colors of light?

This Q&A is about light colours. Paint colours are substances, and different from light colours.If you hold up a glass prism to a beam of sunlight, you'll see the light form a rainbow of colours. This is called the spectrum. It consists of all the colours that make up "white" light.Although you might be able to see seven colours in the spectrum, the white light is really made up of three basic colours. These are called the primary colours because they cannot be made from any other colours. The primary colours of light are red-orange, green, and violet blue. The other colours you see in spectrums or rainbows are made by a mixture of the primary colours.When the naked eye looks at the spectrum, it can see three mixed colours, which are called secondary colours. The secondary colours in light are green-blue, yellow, and magenta-red. You can produce these colours by mixing the primary colours in certain combinations.


How can a wide range of colors be obtained by using only four colors?

If your four colours are the three primary colours (red, blue & yellow) and white the answer is easy.By mixing the primary colours (two at a time - equal amounts) you get all of the secondary colours. By varying the proportions of the primary colours you will get the tertiary colours.By mixing all three primary colours you will get various forms of browns. Adding white to any of these colours will get you various shades, depending on the amount of each.Ultimately you can produce a wide range of colours and shades.
