Colour is present in our daily lives everyday, from sunset. We all know what colour is, however it is some way difficult to give a definition. We could say that colour doesn´t exist cause it totally depends on the light. If there´s no light there´s no colour.
Colour is actually a sensation or impression, it is thought our brain has when it receives information from the eyes. It travels throught the air electromagnetic waves. Those waves come from the light the object´s surfaces reflect.
So there are basically two types of colours: Colored Light, additive colour, is a little harder to understand and explain and it can be studied from the Physics area of knwoledge. Material colours, also called subtractive mixture, are easier to understand and are all of them based in colored pigments mixed with a binder, both of them are the main ingredients for any paint.
Colour Harmony studies all types and classification of colours as well as the ways to combine them in compositions.
