What color is planet Neptune?

Answer 1

blue

Neptune, the farthest planet from the Sun in this solar system, is blue in color. Looking at Neptune from Earth (as seen in the Voyager 2 snapshot), there is a great dark spot on the left and a small dark spot on the lower right. Obviously, the location of the dark spots will change, depending on where the person is and what time of the day/month/year it is.
Pretty sure its blue..idk go to Google.com and go to images..but i think it is blue

Answer 2

Neptune's colour is bright azure blue. Or so it appears to be.

The colour is caused by the red spectrum of the dim sunlight being absorbed by the methane in the atmosphere and the blue spectrum of the dim sunlight reflecting off the methane.

Whether the planet really is blue or whether the blue is an illusion caused by the blue spectrum being reflected back into our telescope lenses is open for debate.

Answer 3

Blue.

It can sometimes be hard to tell with astronomical pictures whether they represent what an object actually looks like, or if they're colored using information that really isn't available to the human eye, like features that only show up in the infrared or ultraviolet regions of the spectrum.

However, the picture in the related links was taken by Voyager, and is reasonably close to what you would have seen had you been on the spacecraft with a telescope.
Neptunes colour is blue, from the ethane in the atmosphere.

Answer 4
