I would like to be able to change the colors of the big icons in the About section. Is there custom css that I can add or somewhere to change?

I updated the style.css

.big-icon .icon {
display: block;
color: #f5eee3;
font-size: 85px;
height: 150px;
background-color: #c30e03;
text-align: center;
-webkit-border-radius: 50%;
-moz-border-radius: 50%;
-o-border-radius: 50%;
border-radius: 50%;
-webkit-box-shadow: inset 0 0 0 4px #c30e03, inset 0 0 0 8px #F5EEE3;
-moz-box-shadow: inset 0 0 0 4px #c30e03, inset 0 0 0 8px #F5EEE3;
-o-box-shadow: inset 0 0 0 4px #c30e03, inset 0 0 0 8px #F5EEE3;
box-shadow: inset 0 0 0 4px #c30e03, inset 0 0 0 8px #F5EEE3;
}

Cleared cache etc <ctrl>f5 Still shows default red.

Am I missing a place?

Thanks
