@jmspool. I'll try that when I get back and post it (I'm just playing around in Paint, frankly)
Also, I like the idea of traditional colors, and it'd be interesting to look at historical flags.
Blue for Savoy (Italy), red for the Ottoman Empire, Yellow for Imperial Russia, for example.
Green could be Austria as that shows up in the Hungarian side, but France and England are tricky because they're, well, red, white and Blue as options. As a football fan, I'm used to seeing England in white. So france gets the light blue?
