Hypomelenistic means a decreased amount of black pigment. And, a decreased amount of black pigment is a decreased amount of black pigment whether it's naturally occurring
but it's not decreased in a naturally occuring population where every milii is that colour, it's a bit like saying a red levis is Hypo because you can get black ones....or maybe they are Hyper's

.... Now I'm not saying all of them are a load of BS, there are some very nice ones I'd be glad to call Hypos posted in this thread, but the vast majority seem to be just normal milii.
