Mealy Bay's

Ok, so I have a Mealy Bay mustang stallion, Spirit's Chess, but I'm not quite understanding why he's called a mealy bay but the custom creation when I do everything he has just says it's a bay??

His genes are Ee Aa gg crcr dd chch Ff zz Pp stysty Rbrb ++ Oo spsp lplp patn1patn1 patn2patn2

The pangare gene (Pp) is what makes him mealy. The custom horse creator will show the base color without the modifiers. For example, try making a silver bay. It will also just call it bay until the horse is actually created. 

Thank you! That makes a lot more sense now!
