Description of problem:
The gnome terminal (the xterm accessed from the taskbar) does not properly
implement the rendering escape sequence when the color yellow is specified.

terminal to produce the character seguence `redgreenyellow' in the named
colors. This fails on the Gnome terminal but works on the color xterm.
