Actually, all grey horses, including those with black skin, are ridiculously prone to melanoma. About 80% of grey horses have melanomas, in fact. Mine has one in her lip and about half a dozen on her tail/dock area (all are each about the size of a pea). I used to swear I wouldn't have a grey for that reason, but, well, no good horses are a bad color, right? And more info you didn't really care about . . .most "greys" with pink skin are not genetically grey (although they are grey in color); they are the combination of chestnut and a strong dilute or cream gene. That said, how interesting all this variety in issues is. I know too much white as an overlay can cause problems in some breeds--deafness, etc. And in horses an overo paint horse which comes out all white has a genetic defect called 'lethal white' and a zero chance of surviving.
