In physics, sure, but biologically melanin is natural sunblock. It's why blacks get vitamin D deficiency and brittle bones the further north they move, where the sun's rays aren't as intense as at the equator.
If Kryptonian DNA is somehow empowered by solar radiation instead of denatured/destroyed by it, they would be fair-skinned to absorb as much sunlight as possible.
Actually that makes more sense, since black reflects less visible light than white does.
But still, I don't think the casting directors were worried about accurate physics.
