I have used thin Masonite in the past. Being a frustrated artist I put the Masonite rough side out. Paint adheres better to the rough side - at least that's my opinion Then I painted it with cheap blue house paint mixed with white - how blue is a personal matter. Any cheap paint will do.
Once that is dried I'd sketch in hills, mountains and the like with charcoal. For painting I used artist's acrylics. The advantage of using the housepaint first is that it is way cheaper than tubes of acrylics and it gives a nice clean light palette.
The beauty is that if you mess up or improve your painting skills, all you have to do is repaint.
Do what I frequently do - look at the clouds, note the colors. I've have seen clouds that have a tannish color and shades of purple are often prevalent.
