Many buffs have some black in their wings and tails. IFF instead you see a chocolatey brown colour in these areas, the bird likely carries dun. If you see black, it does not carry dun.
This is dun:
Bird in front has two copies, bird in back has one.
Frizzled bird has two copies of dun.
Anyways, that colouring is the colour you would see in the lacing on a dun-laced bird. The interior of the feather would be ground colour (red, buff, golden or silver).
