I'm not a huge fan either.
Everytime I see one all I can think about is sunburn.
I'm sure not all of them have that problem, but having worked with lots of traditional white horses that did and other white livestock with sunburn issues..... they make me shudder a little, and remember the blistering sunburns I got as a fair skinned kid.
(Back before parent believed in sunblock!)
Blue eyes I do find interesting though.
My horse has one blue and amber eye and one green and pale amber eye so I had better be a fan of weird eyes.
