It must feel great to have been able to hang them out!
I've been finding a lot of Mamou fur, and probably some Uhura fur. Uhura is all black, and while most of Mamou's fur that's found is white, some is dark also.
Today, there was a black hair on my forearm. My arm hair is so light blonde it's almost clear, so I was surprised that I'd grown a single black hair. I'd blown at it, and it didn't go anywhere.
So, I picked up a magnifying glass, and there it was, the same basic size as the rest. I flicked it with a nail, and it was not from me. From one of the cats.
One of my covers is dark, and has white fur on it. So, I need to de-fur it. Darn. Good luck with yours.
