Some pigments are man-made, or synthesized. These include white lead, blue frit, Alizerian crimson, and Prussian blue. the ability to synthesize pigments lowered the cost of acquiring colors for oil painting.
In order for a biologist to sepearate leaf pigments, he should use chromatography. Hope this helps because I too, had to answer a question just like this for biology!

Paper chromatography can be used to separate pigments in plants. The pigments are separated into chlorophylls (greenish colors) and carotenoids (yellowish colors).
Chromatography works by separating inks into the different colours they are made of. You see, the paint is a solute and if it is added to a solvent and dissolves you have a solution.
Minerals or purified salts (pigments)
Primary colours (not pigments) are red, green and blue.

Most prehistoric rock paints were done using natural earth pigments such as red and yellow ochres, clays of various colours and charcoal.
Two colours are complementary if lights of those colours add to make pure white light. Complementary colours are not the same as complementary pigments (or paints).
They are primary colours. The primary colours of light are red, green and blue, and the primary colours of pigments are yellow, red and blue.
