Hi and welcome to Frog Forum!

I have seen a picture of a yellow variation of the red-banded rubber frog. I understand that the stripes can vary in color: red, orange, yellow, or white. The particular picture that I have is of a frog from Swaziland and has yellow stripes. The source is from a book called, "South African Frogs" by Passmore and Carruthers , page 108.
