Background colour in Key Editor

I don’t think there is a solution but here goes. I’ve searched but can’t find an answer. Is it impossible to change the background colour in the Key Editor from black/grey to white as in revious versions ? I thought I saw a thread where someone very kindly offered many alternative colouring.

Preferences/User Interface/Color schemes
