Tinted paste?

Can you tint the glue or flour mixture before you start to build your structure?

I've never tried this, but I'm sure you could! I'm sure a few drops of food coloring, or even acrylic or watercolor paint would work. I don't think it would give you a ton of color though, because you are applying such thin layers of paste, but with the right kind of paper it might give you a really nice looking result. I'd love to see what happens if you try it!
