Someone asked about normal color for a Whites. I posted this to show how different they can be.
Both of these are healthy adults and long-term captives (four years). As you can see the color difference has nothing to do with camouflage strategy. The green one is always the same color, day and night. The brown one is brown all day and turns pale, milky green after lights-out.
The only color I worry about is blotchy colors or neon-green spots (not to be confused with white freckles, as you see here).
