Aside from the style customizer, which is a Vision thing, the key to the question is to use an expression binding to translate your tag values into a range of colors or indices for colors. Whether Vision or Perspective. I highly recommend you bind the source tag to a custom property (perhaps indirectly), and then use that property in your expressions or styling.

Note that one "pulls" the tag into the UI for evaluation--you don't "push" from the tag to the UI. That is, don't try to do this sort of thing with a tag event or in a context/scope outside the UI.
