Change color of h2

Hi,
I'm not sure if anyone asked this before, but please help: How can I make change the color of h2 title (i.e. "Looking for the summer?")? I've tried to make change h2 in template_css.css: I add

h2 {
font-family: Arial, Helvetica, sans-serif;
font-size:15px;
font-weight: bold;
color: #1216c6;
padding:3px 0;
margin:0;
line-height:16px;
}
but failed.

Please support.
Thanks.

You can put:

color: #1216c6!important;

I made it done. Thank you very much. Highly appreciate.
