The information on creating templates should help you understand how to
modify them as well. When you're in Master view, you can select the
stuff on the master and change colors.
You might also want to read the color schemes pages on my site to
understand how the various items pick up colors from the templates. That
may help you make better choices when creating your templates, and it
will also help you understand about changing the color scheme in
general. http://www.echosvoice.com/colorschemes.htm
