Uranus and Neptune are actually the same shade of blue-green. Apparently, the images that Voyager 2 had sent back in 1989 were artificially enhanced to make Neptune much more blue than would look in true visible light. In addition, it seems that Uranus turns more blue during the equinoxes and more green during the solstices, which might explain why the Voyager 2 images of that planet from 1986 are more green while some of the more recent images by telescopes appear more blue.
