A chromatographic separation of the leaf pigments shows that the colour that we see in leaves is not due to a single pigment but due to four pigments namely-
i- Chlorophyll a which is bright or blue green 
ii- Chlorophyll b which is yellow green
iii- Xanthophylls which is yellow
iv- Carotenoids which is yellow to yellow-orange

Phycoerythrin is red pigment predominantly seen in Red algae. Phycocyanin is blue pigment mainly seen in Blue-green algae.
