Color Contrast: Editor Output heading in code samples

[7mary4]

The heading is currently using color: grey
file: tutorial/css/taop.css

#exerslide-slide .previewHeading {
    margin: 0 0 1.1em;
    color: grey;
}

This should be #757575 to provide the minimal contrast

#exerslide-slide .previewHeading {
    margin: 0 0 1.1em;
    color: #757575;
}

Updated color
