Colour Change??

Hi

Here is the url: http://printplus.ie/print/wordpress

can u see on the homepage in “featuring our specialties” i have changed the box to yellow in colour but its quite difficult to read the white writing is it possible to change it to black just in that area??

@hashthemes thanks that colour code worked! Also could you help with another issue? see link http://printplus.ie/print/wordpress/ when I click into the different pages for some reason my headings are coming up blue?? How do I change that back to black.

Sorted thanks a mill!
