Right... Yes... If it does end up being brown it'll be tint 1 or 2 most likely. :/Wouldn't you also get the possibility of brown eggs?
It's not so bad, but you have to figure out how it works. We are basing the genes off of it but making the calculator easier for beginners to understand.
I sure hope it will be a success.
It's too bad they don't have egg colors. Egg colors are a little too complicated perhaps. You can get a million and three different browns, so you can see where that causes problems. Rose Quartz's egg color chart shows real colors, but uses fictitious names for each tint. Each tint is not controlled by one gene. A lot of it is the color of egg of each parent and the color goes between or sometimes beyond or below her parents darkness of egg.
There are genes for brown and blue, but there are others that are not well known.
