Just tried this on fedora core 3 pretty sure it worked its set for a different hex color on fedora though its #222E45
This is exactly what i got on my fedora machine
grep -r 222E45 /etc/X11/
/etc/X11/xinit/xinitrc-common~:[ -x /usr/X11R6/bin/xsetroot ] && /usr/X11R6/bin/xsetroot -solid '#222E45'
/etc/X11/xdm/Xsetup_0~:#/usr/X11R6/bin/xsetroot -solid "#222E45
Changed those to another hex color easy as pie
Gl and thanks for making this a 2 minute search and howto for me
