Okay, I think I might have an idea of what's going on, if you're using Mozilla, or IE, generally both browsers will let the page decide what colors it's going to use. one thing to check, if you're using mozilla, is to go to tools, then options, click on where it says content, and look for the section that says fonts and colors, choose colors, and make sure the box that says "Allow pages to choose the colors, instead of my selections above" is checked. Mind you this is only one possibility that I've discovered, and there may be others, I will keep looking into this.
Wisdom is knowing what to do. Skill is how to do it. Virtue is getting it done.
That which does not kill you, isn't trying hard enough.
