How to change white theme?

Guys,

I love Alaska; however, a friend has commented that he dosen't like using it as it lights his room up better than his actual light.

Is there a way to change the default white theme to something else? like a deep blue or black?

Cheers all,

Settings -> Appearance.


change the theme from default to one of the other ones...assuming you've got the most recent version
