Chameleon

Chameleon is a lamp shade that changes to match any color you 'show' it... A traditional bulb at the centre of the lamp provides white light above and below the lamp, while an LED ring around this light projects a selected color into the shade, while at the same time preventing the white light from diluting the color being projected.
