Well, just because you're born somewhere doesn't mean your genetics are restricted to only two hair or eye colours. I think it's more that we haven't seen enough Iwa characters to really tell. Most are generic characters made for a single episode or filler arc so they don't need to be too fancy. Others are related, hence the similar eye or hair colours. Deidara is a member of the Akatsuki and no one member of that team was given a lazy design. So, of course he'd look different. Hey, who knows, maybe he died his hair or something. Maybe he even wears contacts :p
