Look at this:

https://en.wikipedia.org/wiki/Trichromacy

Quote:
"The normal explanation of trichromacy is that the organism's retina 
contains three types of color receptors (called cone cells in 
vertebrates) with different absorption spectra. In actuality, the number 
of such receptor types may be greater than three, since different types 
may be active at different light intensities. In vertebrates with three 
types of cone cells, at low light intensities the rod cells may 
contribute to color vision.

Humans and other animals that are trichromatsHumans and some other 
mammals have evolved trichromacy based partly on pigments inherited from 
early vertebrates. In fish and birds, for example, four pigments are 
used for vision. "

Well, you need to specify, to which kind of beings you refer with 
'primary colour'.

Humans have three primary colours, which are called 'red, blue and green'.
