The same happened to me on a project I'm working on atm when using VS Dark Blue. I created a Child of a Room and the interface showed the inherited layers in the same way as your screenshot.does anyone know how to change the color for rooms which are inherited. This room has a parent room so all the layers get highlighted in this color which makes it hard to read. I just wanna know how/where I need to go to edit this.
I tested this with the default Dark theme and it does the same (although in the default theme the light icons are more noticeable at least).
I found restarting the IDE cleared that completely and it used the expected darker settings (in either default Dark or the VS Dark Blue themes). So I think this might be a bug in the IDE itself.
I tried tinkering with the theme files in `Styles/styles_roomeditor.json` but couldn't find a solution - did you ever figure it out?
