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 don't think they look very 'tidy' at shows unless they are coloured specific show classes, same goes for appy coat patterns
