No, at the moment we can only access functions that devices give us directly through verse. The customizable light device can only be turned on/off or un/dimmed.
You can however trigger a Level Sequence through Verse or devices like triggers/buttons. This level sequence can drive your light color dynamically.
Just drag the light from your outliner into a new Level Sequence.
From there you manipulate the Light color.
In the same way you can key and influence all other attributes your light.
