What color is Neptune?

Neptune is mainly bright blue, and also contains areas that are dark blue in color. The color of Neptune is primarily influenced by the presence of methane in its atmosphere. Massive storms that appear as large oval-shaped dark spots have also been observed on Neptune by the unmanned Voyager 2 spacecraft and by astronomers viewing Neptune from the Hubble Space Telescope.

Neptune's atmosphere contains bright cirrus-like clouds that change regularly. Neptune also has six rings that are made up of clumps of dust called arcs. Neptune is a very cold planet due to its distance from the Sun, which is 2.8 billion miles.
