PowerBI – Replace all instances of color?

In PowerBI, I have a bunch of backgrounds that are one color (say #289e63) and I want all such instances to be #9015d6.

Is there a way to do this project, or page, wide without having to individually find each instance?

Worst case I just do a “Find/Replace” on ALL instances of this color in the event of just selecting the BACKGROUND Color itself isn’t available.

Dragging the model in to a TMDL view doesn’t seem to include formatting, so I can’t find/replace there.
