Some colors will breed true depending on their genetic background. Since most breeders collony breed this means each bird can be holding SEVERAL different colors under it's phenotype (visual color).
Now, if you finda breeder who's been selectively breeding thier birds for years, you may be lucky enough to be told what colors you can expect. Dominant colors can produce the color you're looking for, recessive colors you may have to more selectively breed to get. Button quails are colorful, so you'll get an assortment in no time!
