Here's a sample set of 20 symbols (PNG files) from my Topographic Mountain set. These assets only consist of shading (no color). The bottom image is an example of how easily you can color them in Pohotoshop or Wonderdraft. Paint underneath the symbols to achieve desired mountain coloring.

I've had a couple people ask if I plan to include painted assets. Right now I have no plans to do so. Pre-colored mountains would make it harder much harder to blend multiple mountains together, and everyone's mountains would look the same. Leaving them to be colored in the application of your choice means much better blending as well as much more original looking mountain ranges.
