You can change how IE or Firefox display the colors of Web pages. You can either use default Windows colors, or specify your own color choices.
For IE (version 8, other versions might be slightly different): Go to Internet Options...General Tab...Accessibility. Check the box that says "Ignore colors specified on web pages". Click OK. Now click the Colors button. If you want to use the default Windows settings, check the box that says "Use Windows Colors". Otherwise leave it unchecked and select the colors you want for each item.
For Firefox: Go to Tools...Options...Content. Click the Colors button. Un-check the "Allow pages to chose their own colors, instead of my selections above". If you want Windows colors, check the "Use system colors" box, otherwise un-check it and select your colors.
Play around with it and see what works for you.
