Change The Category Color

Great theme!

I’ve been searching for this resolve but there are no clear steps on how to change the color.

I tried checking out this:

there’s some issue with ‘&’ in category name which prevent the color to work. you can change it to ‘and’ to solve this.
its in lib/templates/breadcrumbs.php

But I can see where in the breadcrumbs.php should be edited to have a custom color.

I also checked the Appearance -> Theme options -> Category Color but nothing has changed.

Where is the breadcrumbs.php can we edit the “&” in category name?
Is it the $category[0]->name?

Is the category name?
<?php echo get_category_parents($category_id, TRUE, '&nbsp;&nbsp;&raquo;&nbsp;&nbsp;'); ?>

Thanks you.
