A Platinum Pearl rat looks very much like a colder, greyer version of Pearl with red eyes rather than black. It is a pale color with a creamy undercoat, a cold bluish cast, and grey tipping on each individual hair.

Pe/pe m/m g/g

Since the rat is essentially a Platinum rat with the Pearl gene acting on it, it must be a Mink-Platinum rather than Red.

URS (provisional)

"To be an even blue cream undercoat with each hair tipped with blue gray evenly over the whole animal. Belly fur to be a pale blue cream and foot color to match top. Eye color ruby."
