Stupid name for a planet!
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!).
