[1.11] How to create a mob spawn egg

[Frost2779]

I'v digging around in the source code to try and find out how it is to create a mob spawn egg for a mob and so far I have been unsuccessful, and when i try and google it I only find out of date videos. How do i go about creating a mob spawn egg?

There's an overloaded method of

EntityRegistry#registerModEntity

which takes 2 integers: the primary and the secondary color.
