That's a bad solution - this checkbox is unfortunately named, it should be
named "apply styles' - it govern not only colors, but also button styles,
button placements and fonts in gtk apps

The correct solution is to add following to you .xsession file

(
sleep 10
xrdb -all -query|sed -e 's#[A-Z_]*BACKGROUND# gray90#' \
-e 's#[A-Z_]*FOREGROUND# Black#'  \
-e 's#[A-Z_]*HIGHLIGHT# White#' \
-e 's#[A-Z_]*LOWLIGHT# Black#'|xrdb -merge
) &
