Change foreground and backdround colors

[erentar]

Which files do I need to edit to change the drawing colors?

Unfortunately, colors are hard coded to green. Only the green intensities are handled by constants at the top of tube.c

To change to other colors that green, look in tube.c at all instances of cairo_set_source_rgb

Hope that helps.
