Thank you so much! The coloring of the railing worked. I will look at the rest of what you told me about transparency in windows. I'm working on a really cool looking 5 pane window with a curved window above the main pane. They are rather popular in home construction in my area.

This is a preview of what I want it to look like (I'm not done with it yet):

I'm sorry I didn't realize that you had to edit the text file itself. I thought it could be done by the Art Of Illusion program itself.
