How to alter colors in mac/cocoa text views

Question

Is there a way to alter the standard background and text colors in cocoa text views throughout the mac os? Since the same text system is used by textedit, mail and other programs, I imagine there is an underlying preference that could be altered. Any ideas how to access it?

Just to be clear, I don't mean simply to alter the document colors. This shouldn't be setting a background color or text color as document formatting. I'm just wondering about how I could make all of these text views use different defaults when displaying documents (e.g. white on blue, rather than black on white).

Thanks!

There is no supported way to do this but you might achieve it with a custom Application Enhancer module. Note, however, this is a very controversial subject as poorly-written APE modules (or bugs in Application Enhancer itself) can cause a whole lot of pain in very unusual places (and blame is often placed on the wrong developer as a result).
