Using alpha transparency here doesn't do much; also, try to base the color on one of the colors defined in Foundation:

    // We use these as default colors throughout
    // $primary-color: #008CBA;
    // $secondary-color: #e7e7e7;
    // $alert-color: #f04124;
    // $success-color: #43AC6A;
    // $warning-color: #f08a24;
    // $info-color: #a0d3e8;

We can of course change these colors in `settings.scss` if they are bad, but its good to have a general "color scheme" for the whole site that you can change in one location. This still works though!
