10, so do I, I was just experimenting with my graphics tablet one day and came up with Thor [the one with the yellow markings, in the link], then designed Freydis [the grulla tobiano/splash/sabino/frame mare, if I remember her genetics correctly]. They're Luce's parents, from the genetics I decided for them he had to be silver dapple black dun [is complicated but I can explain if you want] and could have had any combination of pinto markings. His "Flash Marks" could have been Yellow like Thor's, or Prismatic like Freydis's.
Actually designing silver dapple black dun was an entertaining prospect, considering I've never actually SEEN one [I don't know if anyone's ever bred one??] so I had to figure out what he was 'supposed' to look like based on my understanding of the genetics. Fun fun. He sort of looks like a Siamese, Burmese, Birman or Ragdoll cat - you know, chocolate seal point? - but that's what I would expect to see from the genetics. I don't know how Silver and Dun interact in real horses :P
Edit; silver dapple black dun is also known as silver grulla, but it gets confusing to use that term because some people use 'silver grulla' to describe a particular shade of just plain grulla/black dun...
A CLEAN SLATE FOR THE FUTURE
