Answer 1

You can separate the color and background from the button and create another class just for the those properties. i.e. .blue and .red
Then you can move those properties inside those classes applying also the :hover and :active selectors.
In case you want to change color, change the html and change the class blue into red.
HTML
<div class="button blue">Click me</div>
CSS
.button {
display:inline-block;
padding: 10px 15px;
-webkit-border-radius: 4px;
-moz-border-radius: 4px;
border-radius: 4px;
border: solid 1px #20538D;
text-shadow: 0 -1px 0 rgba(0, 0, 0, 0.4);
-webkit-box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.4), 0 1px 1px rgba(0, 0, 0, 0.2);
-moz-box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.4), 0 1px 1px rgba(0, 0, 0, 0.2);
box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.4), 0 1px 1px rgba(0, 0, 0, 0.2);
-webkit-transition-duration: 0.2s;
-moz-transition-duration: 0.2s;
transition-duration: 0.2s;
-webkit-user-select:none;
-moz-user-select:none;
-ms-user-select:none;
user-select:none;
}
.button:hover {
background: #356094;
border: solid 1px #2A4E77;
text-decoration: none;
}
.button:active {
-webkit-box-shadow: inset 0 1px 4px rgba(0, 0, 0, 0.6);
-moz-box-shadow: inset 0 1px 4px rgba(0, 0, 0, 0.6);
box-shadow: inset 0 1px 4px rgba(0, 0, 0, 0.6);
border: solid 1px #203E5F;
}
.button.blue{background: #4479BA; color: #FFF;}
.button.blue:hover{ background: #356094; }
.button.blue:active { background: #2E5481; }
.button.red{background: red; color: yellow;}
.button.red:hover{ background: green; }
.button.red:active { background: pink; }
