TERM is correctly set. I did this in iTerm profiles menu item
$echo $TERM
xterm-256color
$
The styles used in Dired are all in form like this: "const (withFg
XXX)", where XXX are the color names defined in Style.hs, such as
green, blue, yellow.
A typical snippet for adding overlays in Dired looks like this:
...
moveTo pos >> moveToSol >> insertN [mark] >> deleteN 1
e <- pointB
addOverlayB $ mkOverlay UserLayer (mkRegion (e - 1) e) (styleOfMark
mark)
...
where
styleOfMark '*' = const (withFg green)
styleOfMark 'D' = const (withFg red)
styleOfMark _ = defaultStyle
Also, the highlight color for searched terms becomes weird.
The original style is white foreground on pink background on my
terminal, now it becomes black foreground.

screenshot.
Hope it helps,
