I think the different blond colors come from different factors. Some localities have unique coloring in general or even individuals from the same area have different coloring sometimes. Some people breed pairs with the same or similar coloring to keep a unique look and others have bred different locals, colors and pattern types to see what they produce. Someone like Dusty might be able to elaborate on this as he has studied trans-pecos in great detail.
My understanding with the mustard blonds is Craig T. bred ones with much of the same color(a deeper orange or mustard color than other lines of blonds)to reproduce their unique color. When I bought mine from him as yearlings they had a defferent, more orange color than other lines I had seen. They vary somewhat. As you can see my female, which looked the same color as a yearling turned out to be lighter than my male. Here are my adult silvers which as you can see the female turned out to be not as bright as the male although like the mustard blonds, the silvers are from the same line.
