nikko, you can change it back ( default blue) ..or change to any of the other themes.

but changing the mood is still the same. just click on the mood that is displayed on the top middle of your screen. under where it says Private messages.

to change your theme, click on the arrow tab on the bottom left.

the each have some differences. like the report post feature is different.

let me know if you need some help.

changing the default make us look different than some other forums. hopefully this will help people from getting confused.
