Energy in the form of electromagnetic radiation exists, but "colour" in terms of hue is a discrete perceived phenomenon unique to an observer with individual spectral responses.
That's why we have colour management. The grass might be said to be green but your passing observer, but if you ask them again when a very warm coloured sun is setting the actual colour if your measured it, will be very different, perhaps orange, but the observer will say green because they know grass should always be green. However, the grass is always greener, somewhere else anyway! =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
