Description Michael Biebl 2012-02-06 08:08:26 UTC 
Version: 39
Bug-Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=643689

"systemctl dot" produces a dot diagram which uses the color "darkgrey";
however, dot does not recognize the color "darkgrey", so it produces a
warning:

Warning: darkgrey is not a known color.
Comment 1 Lennart Poettering 2012-02-09 15:24:44 UTC 
Hmm, is there any color we can use instead? Maybe dot knows "darkgray" instead of "darkgrey"?
Comment 2 Michael Biebl 2012-02-09 16:31:36 UTC 
The dot man page says:


       A  colorvalue  may  be  "h,s,v"  (hue, saturation, brightness) floating
       point numbers between 0 and 1, or an X11 color name such as white black
       red  green  blue yellow magenta cyan or burlywood, or a "#rrggbb" (red,
       green, blue, 2 hex characters each) value.

So maybe use "gray" or the #rrggbb notation?
Comment 3 Lennart Poettering 2012-02-09 17:39:28 UTC 
darkgrey is an X11 color, so we are perfectly in line with the man page here.

$ grep -i darkgr /usr/share/X11/rgb.txt
  0 100   0		DarkGreen
169 169 169		DarkGrey
169 169 169		DarkGray

Is that different on Debian?

I get the same output on Debian.
Comment 5 Lennart Poettering 2012-02-10 10:16:14 UTC 
Then this sounds like a bug in dot, no?
Comment 6 Zbigniew Jedrzejewski-Szmek 2012-07-21 07:43:07 UTC 
Right, graphviz has ./cmd/tools/colortbl.h with colornames, and darkgrey is not in it. Debian has graphviz 2.26, and Fedora 2.28, so maybe it's enough to wait for Debian to package the new version.
