How to change the Required Error Style?

I have one more question regarding the overlay/pop up you get when not entering in the "required field" text. Can you alter this? With some color themes the red looks really bad as a complete overlay instead of a pop over message or something more subtle. 

This can be easily changed with the Designer feature, please see this quick video tutorial: http://www.jotform.com/form-designer/tuts/episode9/
