Some color breeds only register horses with a desired coat color if they also meet specific pedigree criteria, others register animals based solely on color, regardless of parentage. A few pedigree-based color breeds, notably the American Paint Horse and the Appaloosa, confronted with the reality of many animals born without the proper color even though they are from two registered parents, have modified their rules to allow registration of animals with the proper pedigree even if they do not possess the proper color. On the other hand, with the prevalence of DNA testing for parentage, many horses once forced into color breed status due to being born the "wrong" color and thus deemed undesirable or of questionable parentage by many regular breed registries with cropout rules can now be accepted for registration.
