You will need to edit the file /storm/admin/includes/custom-css.php, you will see a large number of CSS selectors above the line with this code:
1 | {color: <?php echo $options['general_color_main']; ?>;} |
{color: <?php echo $options['general_color_main']; ?>;}Edit the CSS selectors to suit. You will then need to go to the theme options panel and press Save, this will update the cached custom CSS file with your changes.
