Here is a list of the color codes in the ColorPalette, and the
sections of this ~TiddlyWiki that they affect. Please note that
authors of other ~TiddlyWikis may have configured theirs
differently in the StyleSheet. But experimenting with these will
give you practice so that you can more easily reconfigure the
colors of any ~TiddlyWiki.

background or 'paper', and the text in the title and
