Most leaves are green right? Well actually they're not really green. They do look green though. In fact they are inherently no colour, they reflect colour. The pigments in leaves don't care about green. What they want is red, yellow and blue cause that they can turn into other forms of energy that the plants can really use. The green is the garbage that they reflect away, that we see. This simple exhibit shows dramatically how pigments suck up different wavelengths, or colours, of light.
