Dim inactive split pane should darken foreground not lighten background.

Currently the Dim Inactive Split Pane changes the background color. On a black background theme it seems to lighten the background instead of "dimming the pane".
I think a better way to "dim" would be to darken the foreground colors. What do you think?
