I would like to propose the addition of a variety of colors, like the ones used in GraphViz (http://www.graphviz.org/doc/info/colors.html). I know it is possible to define a new color with the defcolor but it would be nice to have a wider color palette by default.
What I could do is to add these colors as a sort of a color pack that could be accessed by stating e.g., 'msc += color_X11'. This would require a design called 'color_X11' (name to be discussed), which contains all these colordefs. Do you have somewhere a definition of these colors? Could you create a text file listing all these colordef's? Then I can easily add it to the design library and do a quick release.
