Blender UI color theme


From some of the screenshot that I see on this forum, some of the blender artist seem to have some color theme applied to their ui (custom colored button and scrollbar etc…). Is it easy to install such theme? Are they premade or must you roll your own?

File / User Preferences / Themes
Install themes, make your own or use one of the built in presets


Thanks! I’ll lok into that when I get home.

Blend Swap has themes you can download
