So I started to go down the direction of accessing the VP Color via this method.
The following code is my massively large approach to trying to change the VP Color for a Viewport on specified Layout.
I first start by gathering the layers that I want to remain Red.
I then attempt to get the Viewport in a Layout so I can try to change the VP Layer in that viewport for all the layers with a specified string that is not in my list of gathered Layers. I want to change the VP Colors for those layers to Cyan.
I ran some testing by going into a drawing, creating some DeltaBlocks, and linked them to a cloud. This then created two layers both for the DeltaBlock and the Cloud. I then went into a layout, clicked in the viewport, and changed the VP Layer for the DeltaBlock to Magenta. Going back into ModelSpace and it was still red.
Then I ran my code, and the Color for that deltablock was red, and the suspected "VP Color" I pulled was still also red. I was expecting for it to be magenta since I believe I have accessed the VP Color via the GetViewportOverrides using the Viewport I have pulled from the Layout. So I was expecting for the second output to be Magenta.
