As far as I can tell multiocolor means just that. Instead of a single bas cooler scheme, different items have unique colors. This has been an option on Apple Watch faces for a yyear or two now.
Thanks. I was thinking literally, i.e. multi, rather than single, color per item.
It would appear that multi-color has yet to be fully implemented in the current beta. At the present time I can tell no difference between multi-color and blue accent color schemes except in System Preferences > General. 😵â€ðŸ’«
If we knew what it was we were doing, it wouldn't be called research, would it?
