Thanks, I should have read ALL the overloads more carefully to see the one
that included type.
However, this still does not work because the compiler reports:
"'System.Drawing.Color' denotes a 'class' where a 'variable' was expected"
I did find, however, that the following (C#) DOES work perfectly:
DefaultValue(typeof(Color), "Control")
Thanks so much for pointing me to that overload, DOH!!!
