http://www.koinup.com/group/Color/discuss/ Color or colour is the visual perceptual property corresponding in humans to the categories called red, yellow, blue and others. Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. This group is for color/colorful pics of virtual worlds. Wed, 19 Jun 2013 20:03:49 GMT 60 http://buddies.koinup.com/group-192.png http://www.koinup.com/group/Color/discuss/
