Ok, I see what you mean.

So the Call to Action section was meant to have a dark background.

You can change that by editing the style.css file on line 1224 and 1249.

You can also use the following CSS code in the Custom CSS field of the Custom Code section in the Parallel Options Panel.

.calltoaction p, .calltoaction h2 {
color: #000;
text-shadow: none;
