There are ‘Light’ (Colours of Light, RGB Colour Model – Additive Colour Mixing Method) & ‘Pigment’ (Colours of Pigment, RYB Colour Model – Subtractive Colour Mixing Method) Colours. Here we are talking about ‘Pigment Colours’. ‘Pigment Colour’ means any ‘Paint colour’ (which is made up of ‘Pigment’ & which can be in dry powder, paste or liquid form) we use for painting our picture. Acrylics, Water Colours, Poster Colours & Oil Colours are the most commonly used ‘Pigment Colours’ by many Drawing & Painting Artists.

VERY IMPORTANT CHART
PRIMARY COLOURS : Red, Yellow & Blue are called Primary Colours because we cannot get them by mixing other colours. They are Original or Basic Colours. But by mixing Primary Colours, we can get many other colours.
SECONDARY COLOURS : Whenever two primary colours are added / mixed in equal proportions, we can get Secondary Colour. 50% Yellow + 50% Red = Orange. Orange, Green & Purple are 3 Secondary Colours.
TERTIARY COLOURS : When two secondary colours are mixed in equal proportions, we can get Tertiary Colour. Orange + Green = Citron (neutralised primary, yellowish grey). Citron, Russet & Buff are 3 Tertiary Colours.
