Green Text - Comes and goes

When I first started creating my UI, all the Text objects displayed green. The colors are set to white, and they sit on a panel that is white.I couldn't figure out what was happening. After a few days, I'd given up checking it out, and loaded my scene - and everything was white like it was supposed to be.

And it stayed that way until today - All the text is green again. Just the text objects, nothing else. They don't have a Material set on them. And If I change the "color" of the text, it multiples the text against green -- almost like the generated texture is green.

Has anyone seen this before?
