leeshaw on "Sidebar Color"

Can anyone please inform me on how to change the color of my sidebar. not the background but the actual 3 lines. it is light grey right now and i would like it to be black. the theme I'm using is Magnus if you are confused about what i am talking about.

There are many tools available for this kind of CSS work, for example:
- Firefox with Firebug add-on: Help info on Firebug https://getfirebug.com/faq/
- Newer IE/Chrome, etc., have similar tools
- Alteately, try a dedicated CSS resource such as http://www.css-discuss.org/
- Also, consider creating a child theme otherwise all your customization will be overwritten when you next update your theme. Alteately, use Custom CSS Manager plugin: http://wordpress.org/plugins/custom-css-manager-plugin/
