What color is solid methane?

Is it blueish, perfect white or some other color? I am interested because some celestial bodies are said to be covered with methane ice.

• Are you referring to solid methane or methane clathrates? – bon Jul 16 '15 at 11:28

• Very interesting question, particularly with recent discoveries in mind. – user15489 Jul 16 '15 at 11:56
• The answer may have to do with light scattering rather than absorption, but I'm not completely sure. – Nicolau Saker Neto Jul 16 '15 at 12:27
• This article appears to suggest that methane ice is colourless. Scientists haven't entirely figured out what color the ice would be, though they suspect it would be colorless, as it is on Earth – bon Jul 16 '15 at 17:36
