I am developing an astronomy software and need to know the color of each planet in the Solar System, when observed with the naked eye. I cannot find that information after googling for a while. Is there any good source? a RBG color associated to each planet would be ideal but it can be any other color system.
Here are some values found by taking the hue from images, and adjusting the brightness to fit the albedo:
Mercury #1a1a1a Yes it is really that dark
Venus #e6e6e6 or perhaps a bit darker
Earth tricky as it is a mix of colors, and changes over the year seems to average out as about #2f6a69
You might find these surprisingly dark. Planets look like bright dots against the dark sky
First look up what elements the planets are composed of. Then figure out how the elements should react due to the planets atmosphere,light scattering,spin,sun reflection from natural satellites if one or many is present,gravity wave overlaps calculations. Finally how the human eye perceives them. But may I add the human eye will never be able to view the colors in there true form, The technology used to view the planets will not correlate to the human eye. So a composite of what the human eye should observe must be composed. "The amount of details reflects the amount of workmanship, that then could produce a Masterpiece. Its up too you"
