Override.css V1
An override.css file for the EE 2 control panel
Template provided by Marcus Neto
EllisLab has added a feature that allows us to drop an override.css file in our control panel themes folder and make slight changes to the way that the control panel theme looks. This is a simple one that just eliminates a lot of the contrasty color and uses mostly grey. Lots of CSS3 gradients and rounded buttons and less images help speed things up. And this is based off of the Corporate Theme
Basic Install Instructions
Enable the Corporate Theme as your control panel theme. Drop the override.css file into your themes/cp_themes/corporate/css folder and drop the images into your themes/cp_themes/corporate/images folder. Voila! You should now see the different color styles when you log in.
