Color of small h tags

[leeaston]

Is color: #999 needed here as we have .muted to call on? Add's a bit of flexibility if removed and uses .muted as intended.

h1 small, h2 small, h3 small, h4 small, h5 small, h6 small {
font-weight: normal;
line-height: 1;
color: #999;
}

For now, we'll keep it. Thanks for the suggestion though!
