If you are using Outlook Express in "Rich Text (HTML)" mode, then you can change the font color by clicking the "A" in the message toolbar and choosing one of the sixteen colors listed, BUT... you can easily expand your palette with this little trick.
Highlight the text you want to color, right-click and choose "Font". In the drop-down Color menu, select "Custom", then click the "A" to bring up more options.
