At first I thought you had a high yellow too but I don't think so now. I have a high yellow & he is very yellow. Yours is very pretty & seems unique. The colors are "soft".
White and yellow, Calico? How does that gene work? Can that come from shtc parents? (sadly, I don't know what his parents are, but since I bought him as a shtc, I just assume they are something like that..)
