Looking at ancient Greek frescoes for color inspiration. I love the pretty faded blues and golds, and the rusted and burnt sunset colors.
Check out the blue flowers… that’s what I’m basing my flower colors off of. The blue pigment in particular is really neat because it was either an Egyptian Blue, which was made by using the residue of patina from copper (similar to my process of enameling!) or a Minoan Blue, which came from a natural residue. Interesting!
