It's interesting you said that ceremllos are not so popular. Since we last met on the forum, I've got two replys from breeders who don't allow diluted mares to be bred with their diluted stallions and they answered very sincerely that they don't want any competition on their business.
We breed for sport, especially for showjumping. There are two diluted lines in Hungary, both stallions are about 20 years old, and former breeders did not take care of maintaining the dilution rate among the foals, grandsons and granddaughters, so many of their offsprings are not diluted. But they have good sport peformance.
What kind of coloureds do you breed? TWH or other show horses?
