Stanley Kubrick insisted that the artists paint the Earth very pale blue because its albedo (reflected light) is 0.38. Only a few years later, photos from the Apollo missions made everybody realize that this figure is averaged over the pure white clouds and the deep blue oceans. Jupiter and its moons were also intentionally depicted vaguely because of the limitations of ground-based telescopes.Something that had been intentionally ignored is that the earth's atmosphere is extremely thin and would not diffuse the image of the surface. If the planet were the size of a basketball the atmosphere would only be as deep as two sheets of paper. As a result, wherever there is no cloud cover, the details on the surface would be exceedingly sharp, even from the moon. In the context of this film, that was not desirable, as it would call undue attention to the earth whenever it is in the background. This is why the planet was painted in gradients of solid colors.
