"or a color set by VT"

Shouldn't this be in the line above with "Runtime Color"?

Oh so I'm thinking that this operates more like the tab title, which can be set by VT, but the VT title can also be overridden temporarily at runtime the tab renamer.

Also note that I'm not sure that there is a VT sequence for setting the tab color, that's purely a hypothetical

One could argue setting the title to a text string with a VT-sequence to set the background color could reasonably be interpreted as a request / intent to set the tab (or titlebar if tabs are disabled )color.
