How do you change the interest box, contact box, and blurb strip colors? Please help!

interests heading:

.profile .table-section .heading {
   background: #insertcolorhere;
   border-color: #insertcolorhere;
}

contact heading:

.profile .contact .heading {
   background: #insertcolorhere;
}

contact box (and the border around both the box and heading):

.profile .contact .heading {
   background: #insertcolorhere;
   border-color: #insertcolorhere;
}

blurbs heading:

.profile .blurbs .heading {
   background: #insertcolorhere;
   color: #inserttextcolorhere;
}

also I noticed this on your profile - make sure all your CSS is contained in <style> tags!

Thank you so much, I will try this!
