Are you using a child theme or a custom CSS plugin?
No, I don’t. I like other thing and it is not necessery to do a child theme. I’d like to change only this red color in something like grey or blue.
So have you installed a custom CSS plugin?
No!!! I can change the existing css. But where, and what to change?
Changing theme files is not smart – your changes will be lost when the theme is updated. When you have the plugin installed, post a link to your site and someone can help you with this.
Or try using a browser tool like Firebug to see what CSS is affecting that element.

Well, the question wasn’t about that. Never mind… I will try another theme.
