Interesting, I haven't had this happen yet, but then I have most of my mares color DNA. I have left it unknown for the stallion and haven't had any trouble.
I love checking the possiblities. This calculator won't tell exactally what your foal will be, however, it helps you eliminate certain mare/stud combination if your also looking for a certain color. I have one mare who's really easy, she's an EE AA so unless I throw in a creme, silver, or pearl gene I'm getting a bay no matter what I breed her too. She can never throw black but if her foal is bred to a homozygous and has a black I automatically know it will be homozygous for black also.
Two of my other girls are Ee Aa so they on the other hand can throw any color. So if I want to increase my chances for a black I need to breed to a homozyogous black or EE aa. Can still throw a bay but no chestnut.
So the calculator isn't the final say, it's more just a tool to help you get where you want.
