Usually none because the C and P loci are linked as they sit on the same chromosome (#7). What this means is that where ce/ce is inherited, P/P is also inherited almost always because they're "linked." Only very rarely is the link broken and ce paired with p. I think this would be called pink-eyed cream, but I'm unsure about that as there are a few ways you can make pe-cream.
The same goes for all C-locus recessives.
This is why argente creme (proper argente creme, Aw/Aw cch/cch p/p) is hard to get.
