Supported color names of Goo::Canvas (and Gtk2)

kikuchiyo has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,

I'm writing a Gtk2 GUI application that uses Goo::Canvas to plot a data file. (zentara's Goo::Canvas Graphing demo helped a lot: I'm thankful for it.)

I saw in that demo and also in the example scripts that came with the module that it is possible to specify colors with their names, e.g.
my $circle = Goo::Canvas::Ellipse->new( $g, $cx, $cy, 3, 3, 'stroke-color' => 'red', # <===== LIKE THIS 'line-width' => 1);

What I was unable to find is an official list of such color names that are supported by Goo::Canvas.

Come to think of it, I couldn't find a list of color names that are supported by Gtk2/Cairo/Pango itself.

Are these two lists identical?

Am I correct in my assumption that these lists are also identical to that found in rgb.txt that defines color names for X11?

    .... i believe the list is the X11 rgb.txt on linux anyways ..... you might ask on the Perl/Gtk2 maillist for a definitive answer..... the closest thing i see is "perldoc Gtk2::Gdk::Colormap"..... where you can define your own map if you want far as a special Goo map of colors..... i think as a compliant Gtk2 will use whatever your other Gtk2 widgets have available.... one big happy family :-)
