Once you have the stencil in your hands, you can reproduce it in any colors you like. Krylon sells paint in over a hundred colors, as does Montana Gold. You won't have any
problem finding the right colors.
Having trouble getting started with that canvas you always wanted to paint?
Just upload the image that you're using for inspiration, and use the stencil to paint the
first pass. You'll be surprised at how quickly the rest of it goes.
