Orange is a great color for blue eyes, it really makes them pop! I used an awesome orange pigment from a company called TC2 for my lid. I have no idea if they're in business still, I got a few pigments in a bargain bin at the mall a few years back, and it's one of those. The lighter orange is the bright orange in the rainbow stack from Calypso Minerals. I will do a post on that stack at some point.
