Programmatically modify frame color

[vix]

I need to programmatically modify the frame color for a slider control.

I'm able to do this while developing through "Customize control" (see attachment), but I don't know how to do this during runtime.

I think I need a reference to the cosmetic element that represent the frame. Is there a way to do this?

You can't do it with modern controls, but with a classic slider you can use the property Housing Colors -> FG Color.

I can modify the housing color for modern controls too, but the frame is a different element.

I've just added a new idea in Idea Exchange Forum
