What is "MULTICOLOR" color option on the X-Large watch face in watchOS 3?

It doesn't seem to do anything and i don't see any reference to it anywhere.

I'm still on watch OS 2, does the X-Large watch face can have complications now? If so, I guess it should work exactly like the Modular watch face. Instead of having the same color on every part of the screen, each complication use its own.

Yep! That was it. Thanks
