[SOLVED] [1.12.2]Custom spawn egg color same as vanilla spawn egg?

Hello. I have a custom cow mob, and I want its spawn egg to use the same gray color that the vanilla cow's spawn egg uses for its secondary color as my custom cow mob's spawn egg's secondary color (sorry if that was confusing). How can I do this? Is there a class that I can look at to find the color value?

Thanks!

So sorry, just found the class (EntityList).
