My system is running dual monitors at 1600x1200x32bit
primary display is a VGA connection; second is DVI-D
After starting
runemace -q
then stepping into list-colors-display and defined-colors in faces.el
abd xw-defined-colors in term/w3-win.el I've isolated the problem
to w32-color-map
(display-visual-class)
true-color
(length w32-color-map)
271
w32-color-map
(("SystemMenuBar" . 11055248) ("SystemMenuHilight" . 0) ("SystemGradientInactiveTitle" . 10789024) ("SystemGradientActiveTitle" . 6831878) ("SystemHotTrackingColor" . 14399637) ("SystemButtonAlternateFace" . 12632256) ("SystemInfoWindow" . 12632256) ("SystemInfoText" . 6831878) ("SystemButtonLight" . 3947580) ("SystemButtonDkShadow" . 0) ("SystemButtonHilight" . 10329501) ("SystemInactiveTitleText" . 15066597) ...)
(assoc "grey30" w32-color-map)
nil
(assoc "black" w32-color-map)
("black" . 33554432)
However:
(color-supported-p "grey30" (selected-frame) t)
t
(defvar w32-color-map) is defined in w32fns.c
so I can't step into that to find out where the colors are coming from.
I did find another Windows 7 system where the gray colors *are* working
and w32-color-map has 783 elements:
(assoc "grey30" w32-color-map)
("grey30" . 5066061)
That is a laptop with 32 bit color 1440x900 (single monitor)
running Windows 7 x64
As a workaround, I can copy the full 32-color-map from the
other system and eval it on this system, then
(set-background-color "grey10")
(set-background-color "grey20")
(set-background-color "grey30")
all work as expected (I use the same Windows color theme
on both, so the System* colors in w32-color-map are OK for me)
I don't know why w32-color-map (w32fns.c) is so short on my system.
(I've have rebooted - no change.)
