Hi,
If you are using exactly what I gave you it should work. I suggest you add this back to your skin, reset the skin version guid and then if the problem exists use the browser developer tools to determine what is causing the text of the site to change colors. If you can leave the CSS in place I can troubleshoot it further. Without it in place, I can't see why it is causing all of the text of the site to change color.
Thanks,
Joe D.
