There is one cremello stallion I have seen that I liked. ONE.
IMHO all double-dilutes should automatically be gelded or spayed. I don't care how spectacular it is, if it's guaranteed to produce colour, you're GOING to have people rocking up with their free, poorly conformed bitch of a mare, asking if you can please PLZ please give them a free service because your stud's fee is just SEW EXPENSIVE. Or conversely if it's the mare it's also that much more likely to be bred to any old stud just for a pretty dilute baby.
Nothing against dilutes, I have one myself. I just don't like double-dilutes. Don't like the colour and don't like the consequences.
