I'll be using the standard betta genetics terminology for each allele, I didn't use them in the stickied ones, but now that I have a little booklet with ALL of the representations, it'll be a piece of cake. For example, "BlBl" for turquoise, "blbl" for steel blue, and "Blbl" for royal blue. Makes things much easier to understand.
