I love perlinos too!
my all time fave is bay, boring i know but i love them. They go with any colour tack and equipment!
another i love, flea bitten grey. hard to keep clean but beautiful all the same
and my least fave. would be the pinto (sorry paint lovers). I do see the attraction but i dont think they look very 'tidy' at shows unless they are coloured specific show classes, same goes for appy coat patterns
I LOOOOOVE Grullos! Someday, I WILL have one,lol. Providing I can find one with good conformation, temperament, ability, etc...lol. They're pretty rare in the RMH/KMH breeds. I of course love my mahogany bay boy too!
I love the blue roan Tennessee posted. Beautiful! Basically, I don't like the "boring" colors; bay, chestnut, etc. I love grays, though, especially dappled grays. I love color, all kinds of Appy's. I do not like Paints like the one sdf posted, I like Paints like mine with more solid splashes. [Notice the other horse, my bay Qh filly, haha.]
I also like Paints with more color than white, like Spirit posted, as well as pali-paints.
