Customize Option Framework

I’m pretty sure there is an example in the Options Framework sample theme on how to create a color field. How you use the option data in your theme is a different matter. You can print CSS in the header via wp_head hook and use PHP that way. I’m relatively certain this is shown in the sample too.

function wpa_138251(){
 $color = of_get_option('some_color', '#CCCCCC' ); ?>
 <style type="text/css">
    .some-class { background: <?php echo $color; ?>; }
 </style>
<?php
}
add_action('wp_head','wpa138251');
