Photos from the Voyager era show it to be on the border of blue and green, particularly greenish in some of them. On the other hand, amateur astronomers report from their backyards a definite "blue blob". So what colour would Uranus appear to human eye? Was the greenish tint made up as a distinction from Neptune? Or was it some flaw in image processing?

I have always thought that this was the definitive view of the color of Uranus. To my eye it seems steel gray. Maybe some of those here with artistic eyes can comment on this version.
I too despise the ads of the Views of the Solar System site, though I clicked on it and waded through the ads. The image at this site has a decided greenish caste to my eye. I remember hearing that Uranus is less blue than Neptune because the clouds on Uranus are higher than on Neptune and so there is less of a depth of clear methane gas to absorb the red light. I wonder if there is a seasonal effect at work on Uranus. |
