Yii Error Page (change background color)

How can I change the background color of the line causing the error (view attached image)

If I understand the API doc correctly, you have to save your own error views in protected/views/system (or in a theme). The original style in framework/views/exception.php seems to be ".error {background-color: #ffeeee;}"


I am trying to tweak the error page the framework displays itself.

So on the very error page attached, I'll like to change some CSS settings.

I just verified that copying the framework view file to protected/views/system (and tweaking) works as expected.
