Visual perception is a result of light being detected by your retina at the back of your eye. Light of different wavelengths determines colour. Objects that are a specific colour absorb light of certain wavelengths and reflect light at other wavelengths. So if an object is green that is because it is absorbing the red and blue light and reflecting green.
