sort of a pun tbh but reading this ...
There are many reasons why things are the colour they are, but mainly it is due to the absorption and the scattering properties of the material being different from that of the incoming wavelengths of the light that illuminate it.
As a further example: we see green leaves or grass as being green because leaves and grass (and other green plants) use Chlorophyll to change light into energy.
Because of its nature and chemical makeup, Chlorophyll absorbs the blue and red colours of the spectrum and reflects the green. The green is reflected back out to the viewer making the grass and leaves appear green.
Following on briefly to how we see colour... the rods and cones of the eye pick up on the particular wavelength and frequency of green and send the message to the brain. Similarly a ripe tomato is red because it reflects rays from the red end of the spectrum and absorbs rays from the blue end.
was reading up on this stuff omg beyond me http://newton.ex.ac.uk/research/emag/pv/publications/
