Long story short, my turtle has orange lips and face. It's symmetrical. I think she's had this before and it went away, but that time it just looked like lipstick. I haven't fed her anything orange lately, although one of the types of sticks I occasionally feed her is more tan than green. (She's picky and doesn't eat a lot of greens, so mostly repti sticks and Mazuri balls. Recently I have her dandelion greens, but she didn't touch it.)
