Colour filters absorbing light, illustration. White light, composed of all the colours of the spectrum (left), encounters a red filter which only allows red light to pass through it. All the other colours are absorbed. The red light then encounters another filter, for example a blue one, which only allows blue light to pass through it, so no light at all passes through and the observer sees black. | |
