Hi Irvin, you can find all color names that are supported by Tk at: http://www.tcl.tk/man/tcl8.5/TkCmd/colors.htm In general, http://www.tcl.tk/man/tcl8.5/TkCmd/contents.htm is a good reference for Tk. I tried to keep Ltk close enough to Tk so that the Tk reference and many tutorials you can find on the net are still useful to Ltk users. Peter
