Can't change color scheme!

Hey!

In my blog (https://blog.jorgicio.net) I’m using this theme, and when I try to change the color scheme (now it uses the default, Turquoise), it happens nothing. All other options change when I do, but that. I tried uninstalling, reinstalling, watching for options in a database, deactivated and reactivated all plugins I have, and nothing helps.

Please, help.

Thanks.

Greetings!
