Cool Colours W E Warm Colours
Light is the combination of all colour, without light there can not be any colour. This can be found out from the experiment of the prism where at the particular angle, the light enters, splits and forms the spectrum. The spectrum contains seven coloure, which are Violet, Indigo, Blue, Green, Yellow, Orange, Red. This can be abbreviated as VIBGYOR.
The combination of all these colours are White and the absence of any colour is Black. The colours placed in the eastern side of the colour wheel are warm colours and those placed in the western side are cool colours.
Yellow, Red, Blue are the PRIMARY COLOURS.
Mixture of two Primary colours are called SECONDARY COLOURS, those are Purple, Orange and Green.
TERTIARY COLOURS are the mixtures of one Secondary Colours, they are Red-Purple, Blue-Purple, Blue-Green etc.
When Black is mixed with the colour it becomes tint and it is the lightest value of colour.
When White is added to any colour it becomes tint and it is the lightest value of colour.
Hue is true colour without any value of lightness or darkness added to it.
In the case of Water Colours, to add the value of lightness to any ‘hue’, it is advisable not to add White in it but in the cases of Poster Colours, Oil Colours and Pastel Colours White may be added. Many, renowned artists has evolved many technologies of mixing and applying colours but the above is the very general idea about it.
