Whats the Colour Of Your Moon?

So I posted this thought that was... "If you need me I'll be in my own little world."

One of my friends ended up commenting on it asking "whats the colour of your sky?"

Without thinking and hesitating I answered "Green and Orange"

Then after that convo I had the inspiration to make this painting. 

Enjoy

Question. 

What's the colour of the sky in your world?
