 Another person as inglish for a second language..
 The Question reads: "Can you name the Primary Colors?"
 you named 3, you're missing the color Blue.
 

There are no such things as 'the primary colours', because color itself is a function of the (human) eyes and brain.
But 'human eyes' are actually specific to us as human beings and therefore not 'primary'.
What we humans regard as colour is created by three types of cells in the eyes, which are receptive for certain spectra in the visible range, which we humans call 'red', 'green' and 'blue'.
With these three types of cell we can see colours in the visible part of the vast range of possible em-frequencies.
Other creatures have different eyes and can see diffent colours, possibly with a different set of primary colours (for which we have no names).
