Reading Pane in Explorer

[Greg S]

I've changed the background color in Explorer, Explorer Navigation and the Reading Pane on the righ side of Explorer. The reading pane defaults back to the whiteish color when a text/pic etc. is visible in there. I know that it can be changed by changing the Window background color in Advanced Properties but that also changes the color for alot of other elements that I wish not to change. Any way to limit it to just the reading pane when it's active?
