How to change Font Awesome icon colors?

Add the color to the HTML element, like this:

<i class="fa fa-car" style="color:#DDDDDD;"><!-- icon --></i>

Let me know if that helps or not :)

You can also add icon sizing

<i class="fa fa-car fa-lg" style="color:#DDDDDD;"><!-- icon --></i>

<i class="fa fa-car fa-4x" style="color:#DDDDDD;"><!-- icon --></i>

See here:

And there is also css so you can make site-wide changes e.g.:

.fa {
	color: black;
}
.fa-car {
	color: red;
}
.fa-bus {
	color: green;
}
