different wall colors for new and existing construction

[joeybuilder]

Thanks, DJP, for the input; I'll have a go at the workaround. Still, you point out a limitation in the software that, it seems to me, really shouldn't be there. That I can manipulate single bits of wall in all sorts of ways—thickness, layers, wall covering and more—but not its basic color strikes me as a feature forgotten. I'm no programmer, but it would seem that a bit of code would right this little wrong, so it's off to the suggestion box.

Thanks, too, for your dedication to Q&A. Far as I can tell, you're the Chief Answer Man around here.
