@zande Thank you for the explanation I have been reading for.

We had a B while I was growing up (who reached the age of almost 20 born in 1977) which was as close to cream (diluted copper) as we could tell & hazel eyes. I wondered why catching sight of that particular shade was rare since, though there certainly were many when I was young.

If I can ask, are noticeably not-short manes/collars also uncommon? As our B's mane spiked in various ways depending on his mood, it was so helpful in determining what had caused a feet-locking moment mid-walk.
