I gotta mention that the idea of a desert-world Andor goes at least as far back as Shane Johnson's 1989 World's of the Federation book.
Considering the Andorian's colouring and that they're the portrayed as the volotile opposites of the Vulcans, an ice world (opposite of desert Vulcan) makes sense.
I often hear people expressing the idea that blue coloring "makes sense" on an ice world, but I don't understand the reasoning behind that assumption. I'm not aware of any arctic organisms on Earth with blue skin or hair. White would make more sense as a camouflage color. Blue coloring would only make sense as camouflage for an aquatic organism such as a whale or a fish.
All I can think of is that it's by association with human lips turning blue when the body is extremely chilled, but that's the result of insufficient circulation, and it makes no sense that a healthy organism adapted to a cold environment would have the same problems.
