Borderlands 2 TPS-themed Heads

I’m really not sure if it’s really a bug or intentional, but either way I hope this gets sorted out.

I noticed that Maya’s and Axton’s TPS-themed head have white hair. They look bad and half ass, despite of how interesting and different the new heads are.

I don’t remember about Salvador’s, but Zero’s head is colourful in Claptrap’s tone.

Any staff can answer this? Thanks
