Brown hair, blue eyes. yawn
I was blond as a small boy though.
Blonde hair, hazel eyes - they’re mostly yellow, but sometimes they go greener, and sometimes browner. Prior to looking it up on wikipedia just now, though, I didn’t know yellow was an actual colour for eyes, I thought mine were just freaky. I feel more normal now!
No hair, blue eyes.

Now there are some people, my hair stylist for example, who think my hair is dark brown, but they’re wrong. Yeah, it’s got some dark brown in it, but dude, my hair is black.
