Rhino options Advanced key for layout tab color?

I’ve worked up a dark theme by changing some color keys in the “advanced” options. However, I can’t find a key for the tabs and layouts at the bottom. Perspective, Top, etc. Anyone know which key controls the colors of those tabs or whether or not their color can be changed at all.

Hi -

In Rhino 7, Rhino.Options.UiPaintColors.InactiveTabBackground sets the inactive tab color and Rhino.Options.UiPaintColors.NormalEnd sets, among other things, the active tab color.
