Can someone help with explaining this to ds (skin colour etc)

[Nerf]

Ds was talking to dd about Punjab from Annie and was confusing us all by describing him as black. How best to explain black, white and then Asian, Eastern European etc (rather than a colour) . Ds has asd and I am just confusing him by saying that so and so is Indian, not 'brown' but it's okay to describe his cousin as black. (Jamaican).
I am now confusing myself

Yeah he's called Punjab and wears a turban, Sikh is a fair assumption! But the actor who plays him is clearly black.

Okay whole new conversation looming. I've forgotten what ds was confused about now I'm so confused.

Thanks for the link.
