@Serenity-Gwin there's also probably a translation thing happening with the colour description vs actual genetics, I've seen other flaxen chestnut horses called palomino, there's another term for actual palominos (pari?) that seems to be used
Very nicely organised! I've added all the outcrosses and colours/patterns you have suggested except for 'sabino'. The breed already permits white spotting (which is what your examples are). What people tend to call 'sabino' is more correctly called white spotting and represented with a W in the genotype. So those markings are already allowed. Also, since all single cream is now allowed, smoky black is also now accepted
These are not sabinos. They are just called sabino because that is the common name for all these types of white pattern. You are allowed to call them 'sabino' on Equus but you must put W in the genotype. As has been said, white spotting like this is already permitted.
True sabino does not usually look like this. It either produces rather minimal 'normal' white markings or a nearly all-white horse.
I can't find a lot of information on this horse and the TWHBEA doesn't even have a color code for appaloosa... But I also can't find any reason NOT to accept it based on the little I can find... So I'm prepared to accept this but I'd like to hear from others and whether there's support for this or any objections before I go ahead and do that.
