Adjust Skin - How to change the colour of the caption of a view ?

Hi there,

I am struggling with the following (we are still on SAP CRM 7.0):

How can I change the color of the caption of a view, i.e in the below example change the "light blue" of Account Details to a different colour.

I checked in the "How to adjust Skin" Guide, and changed some colours of other web ui elements in the thtmlb_stand.css, but so far did not success to change the color of the caption.

Thanks for your help,

Bernhard
