Request: example showing animated transitions between states

[hamoid]

That's a topic that it's missing from most posts describing state machines: how to animate transitions.

One option is that the animated transitions themselves are states themselves.
(stateGoingFromAtoB, stateGoingFromBtoA).

But I think there must be a more clever way to do that, because doing the above the states can grow exponentially.

Two references:

As for the example, it would be great to have 3 states (R, G, B) and cross fading the color when transitioning between those 3 states.
