Did you try to use hex color specs like '#d9d9d9' instead of 'darkgray' or 'lightgreen'? According to https://www.tcl-lang.org/man/tcl8.6/TkCmd/colors.htm there should be "dark gray" and "LightGreen", but maybe your version of Tk somehow fails to treat the color names case-insensitive resp. "space-insensitive". Best regards Michael .-.. .. ...- . .-.. --- -. --. .- -. -.. .--. .-. --- ... .--. . .-. Space: the final frontier. These are the voyages of the starship Enterprise.
