I've just tried the new X upgrading from 4.3.0 and found the default blue colour
in xterm-color has been changed to very light hue. This looks particularly bad
in Midnight Commander. A simple error I'm sure.
Somewhere between xterm-patchlevels 174 (included in xf 4.3.0) and patchlevel
184 (currently in xc-xorg tree), some color definition in
xc/programs/xterm/XTerm-col.ad have been changed:
diff -u xfree86-4.3.0.dfsg.1/build-tree/xc/programs/xterm/XTerm-col.ad
/data/work/cvs/xfree/xc-xorg/programs/xterm/XTerm-col.ad | egrep
'VT100[*]color' | grep -i blue
If you set add "*VT100*color4: blue3" in your .Xresources or change it
/etc/X11/app-defaults/XTerm-color, you'll have the colors the way you
are used to ...
From upstream Changelog file (http://dickey.his.com/xterm/xterm.log.html), you
can see Thomas E. Dickey's comments for patch #180 (qouted bellow):
# use color resource setting from Debian package for xterm VT100 widget, since
the choice of blues provides better contrast.
# remove color resources from XTerm.ad, leaving them only in XTerm-col.ad
(prompted by Debian package for xterm).
This was fixed for Debian #241717:
