When I enter the Recycle bin or the Network the colors are the same as any other folder except for one thing, the font color.
I have dark background for all folders and a light font color but with the Recycle bin and Network the font color stays black, which is hard to read on a dark background. Only the sort column of the Recycle bin has a white background.
When I refresh the folder the custom dark background becomes white. The sort column stays white and the font stays black. The advantage is that I can read the contents after my eyes have recovered. 
It makes no difference whether I include Recycle bin and Network in the Native display option under Virtual folders or not.
I don't have this issues with the other folders like Collections, Libraries, FTP, OneDrive etc.
Where can I set the font colors?
Why does the background color change after refreshing the folder?
