I can answer for my parents.

My mom has brown eyes, my dad has blue eyes (that change to green). My oldest brother has brown eyes. My 2nd oldest brother has hazel eyes. And I have brown eyes, most of the time. My eyes do change to an odd green color sometimes (it freaks people out that know me when they see that happen, my eyes are normally a chocolately brown

). Growing up, 2 of us were quite blonde, one was somewhat blonde. I never knew I wasn't supposed to have blonde hair and brown eyes until I was about 17 yo when someone mentioned to me how unusual that was.

I'm not so unusual now (as far as that goes anyway

), my hair is a blondish/reddish/brownish color (my dd tells me I'm looking more and more like a browneyed Lucy Ricardo

).
My SO and I both have brown eyes. Our ds has brown eyes (just like mine), with brownish/blonde hair. Our dd has sky blue eyes (her paternal grandfather has blue eyes, and I've already mentioned my dad's eyes), and many people call her Cotton Top or Towhead since she is so blonde.
