Probably not, since their skin is black. Like all horses, the only pink skin they have is where they'd have white markings if they weren't all-over grey.
Greying is caused by a gene; it's not really a coat color, although we refer to it as such.
The only places Casper and Cloud sunburn are where they have pink skin, just like any other horse.
