Not sure how you set up that child theme style.css file -- did you copy everything from the parent css file into it? That's not typically how child themes are set up -- though it can work -- just a lot harder to keep your CSS code organized...and if you do that, you surely don't need the @import -- that just functionally duplicates all the CSS...
Anyway, the CSS code that is determining the color is on line 656 --
#slider h3 {
color: #6B96A8;
font-size: 18px;
line-height: 30px;
margin: 0 0 20px;
text-shadow: 0 1px 1px rgba(0, 0, 0, 0.5);
}
I think your page layout is a bit messed up-- it looks like the slider section should go inside the div with class="two-thirds". As is, you have everything in the header section and the right side section inside the slider section -- so you have major layout formatting problems.
The CSS also has a lot of duplicate code...
You also have some mark-up errors so you might want to deal with those as they will affect layout problems.
