Rat color id please

Thank you, that's what I was looking for. . So does varigaited mean mottled coloring through out? So what makes them a Berkshire? Is Berkshire the coat pattern, not color?

Yes on variegated. Basically a variegated has the hood (with or without a blaze or headspot), but instead of a stripe (broken or solid, an ideal hooded has a solid stripe) down the back, they have spotting like a dalmatian. The Berkshire is a marking: white feet, white belly, and sometimes a headspot or blaze, ideally half the tail is white but that doesn't always happen either. Irish would just have a splotch of white on the belly instead of the whole belly being white. "American Irish" is more of a circle, "English Irish" is a perfect equilateral triangle between the front legs with the point pointing at the back legs.

ETA: And the genetics for all of these markings are all related and on the H-locus. Hooded is a simple h/h, Berkshire is a H/h, where self (completely solid, no white at all) is H/H. The variegated, bareback, dalmatian, Irish, and several others are modifiers on that locus. I can't remember all of the codes used for the different genes, but I think they include (might have dominant/recessive mixed up too) h^i, H^re, and H^ro (this is the "Robert" gene, aka Essex).
