Yeah Kevin. It was the amel Black Rat that was introduced into the Yellow Rat x Everglades x Black Rat to later make a homozygous albino product of all three. Bill Love started these in about circa 1990.
As everyone mentioned, they can be HIGHLY variable, and they can be anything from light and pale with a barely discernible pattern, to VERY pink, or pinkish/orange with strong blotching. I have seen some a friend of mine had years ago that were more of a solid pink as well.
Here is a real nice looking one a lady picked up from a rescue center a couple years ago.
