Looks like OW Visuals has switched to Fontawesome icons. I don't know if you just want to change the color, or change the icon all together, but here is the css you will be working with. Ex. the icon is on the content line content: "\f041" the color is simply on the color line color: #33bdeb
If you are looking to change the icon, you can go here to the Fontawesome website to see all of their available icon.
On the Fontawesome site you will see a list of icons. Click on the icon you are interested in, and a new page will open showing that icon. Just below the icon sizes you will see a unicode. That unicode is what you will be using. Just change the unicode itself leaving the /, and " ".
You can add the css below to your custom css for the theme in the admin panel.
/*Map marker icon*/
.red-text::before {
content: '\f041';
font: normal normal normal 60px FontAwesome;
position: relative;
margin: 10px auto;
bottom: 0px;
color: #33bdeb;
display: block;
height: 80px;
width: 80px;
}
/*phone icon*/
.blue-text::before {
content: '\f095';
font: normal normal normal 60px FontAwesome;
position: relative;
margin: 10px auto;
bottom: 0px;
color: #f76f03;
display: block;
height: 80px;
width: 80px;
}
