How to change Treeview node background color with Bitmap Style Designer?

[Gord P 17]

I can change the color of most things (so far) but the default background color for a node item in a treeview is light blue and I can't figure out where to change it.  It must be possible because some of the styles, mostly the dark ones, have a color other than light blue.

Has anyone been able to change the appearance of a Treeview via styles in any way (the Bitmap Style Designer or something else)?  I found out how you can adjust some things if you turn off styles, but that is not what I am looking for.

 

I am just wondering about making a change as simple as this

  to this  

for example.

 

I'm using VCL by the way, and 11.3.  Thanks
