XStoreColor/XStoreColors only work on writable colourmap cells, which
means that they only work on visual types with a programmable colour
look-up table, i.e. GrayScale, PseudoColor or DirectColor, and not on
StaticGray, StaticColor or TrueColor visuals.
It's likely that your application was specifically written for a
PseudoColor visual (probably 8bpp), and won't work on any other visual
type, but your X server is operating at 16/24bpp and only provides
In which case, you can configure the depth and visuals in xorg.conf,
Modes "1280x1024" "640x480"
Alternatively, you can use the -depth and -cc command-line options
when starting the X server, e.g.
/usr/bin/X :0 -depth 8 -cc 3
