Q: Do turtles have color vision?
Q: Do they care about the colors of what they see?
A: Yes, in a way. I don't know of any color
research with turtles. Some lizards use colors (like anoles with
a red dewlap). And fish, of course.
I have one turtle who definitly prefers white foods, and he will
chew on anything white that I put in his cage. This finicky eater
will eat tofu and egg whites, only because of their color.
Q: So, should one choose or avoid specific colors when setting up
a turtle environment?
A: Personally, I hate pink, so I assume my turtles hate it, too, by
I don't think color matters too much. I tend to use "natural"
colors for animal stuff, like brown, gray, green, or black; and
I avoid red (an aggressive color).
