How to change color for Site Title, Menu background and Post/Page Title?

Hello, I would like to now if there is a Custom CSS Stylesheet code to change the color for

– Site Title
– Page or Post Title
– and to change the background color for the Menu.

I know that there is an option to change a few color option under the Theme Options > Colors menu, but that still gives me black Menu background and also black Site Title and black Post Title. It only changes their color if someone moves the mouse to that area.

What I would like to do to change their color permanently.

Thank you for your help!
