Why Red, Yellow and Blue?
Our name Red Yellow Blue refers to the primary colours and universal character of light. This historical set of colours symbolizes unity and oneness, that we are all universal human beings, born free and equal in dignity and rights. |
Red, Yellow and Blue are primary colours. They can not be made from any other colour. They are primarily used in art and art education, particularly painting. Contrary to popular belief, there are actually two types of primary colours, additive primary colours and subtractive primary colors.
Additive colours are colours that are associated with emitted light directly from a source before an object reflects the light. These colours are red, green and blue. These are the colours we are probably most familiar with in association with television, and computer displays.
When equal amounts of Red, Green and Blue light are combined, they produce white light. By adding the colours together to produce white, we call these additive colours. Red, green and blue are the "primary" colours of white light. The combination of all three of these colours will result in white. This is called Colour by addition and is direct way to prove that all of these three colours do indeed come from white light.
Subtractive colours are colours that are associated with reflected light. In this case the subtractive colours are Red, Yellow and Blue. These are the colours we are probably most familiar with as the primary colours from school or art education.
When equal amounts of Red, Yellow and Blue pigment such as paint is combined, black is produced. By adding the colours together to produce black, we call these subtractive colours. We use subtractive primary colours when we are mixing paints or inks. In the case of inks and printing, the colours used are Cyan, Magenta, Yellow and black. (CMYK for short).
Secondary colours are created, if two of the primary colors are mixed together.
When the subtractive colours are mixed, they produce three other secondary colours. These are: green, orange, violet/purple.
Tertiary colors are combinations of primary and secondary colours.
There are six tertiary colors; red-orange, yellow-orange, yellow-green, blue-green, blue-violet, and red-violet. |
