First, this is one of the best most user friendly plugins, for me, I've yet to use.  After scrolling through about 10 pages I couldn't find a post which answers this question and apologize if it is here.

I've searched line upon line in the CSS Styling to change the text colour after a person submits the necessary or required information.  In this case the default message says "Thank you for your comment!" 

I can not find how to change the colour as it appears to be a very light blue-white text colour and conflicts wih my background and is making it very difficult to see.

I have selected the button to have a message appear but, would like to change the text as I would prefer not to have this message appear.

Thanks
