Stupid name for a planet! :P In a sense, what I've done here is a pointless exercise because we know that Uranus is a cyan colour and we know that when we split the light from Uranus we get an optical spectrum like the one I posted in the previous thread.
On the other hand, all I actually got was a Zero Order image of Uranus as a pure white over-exposed blob, and a low-res optical spectrum. You should be able to sum the spectrum to show the visible colour of Uranus. All I did was compress the bar spectrum of Uranus down to one pixel in width using Photoshop. This effectively averages the colour but produces a dim, dark colour representation, not helped by the spectrum being a little under-exposed. To increase brightness and intensity to complete the 'summing' I applied levels and saturation, somewhat arbitrarily but hey! ;)
My processing skills are somewhat Neanderthal and I'm sure there'd be better ways of summing the spectrum (but hopefully not returning to the white of the over-exposed Zero Order image!).
