Red and green filters absorbing light, illustration. White light, composed of all the colours of the spectrum, encounters a red filter which only allows red light to pass through it. All the other colours are absorbed. The red light then encounters a green filter, which only allows green light to pass through it, so no light at all passes through and the observer sees black. | |
