Problem with colours in posts

Hi Sakin In the Catch Kathmandu theme I have changed the colours. Almost all changes work. There are only some exceptions in the posts. Please have a look at my blog page http://tambourenverein-elgg.ch/news/ There you have type of posts like "Video" or "Bilder". If I point with my mouse (mouse over) for example on "Video" it turns from grey to blue (the original blue of the theme). But it should turn to red. The same problem occurs on some titles in the posts. For example the title "Dani Benz gibt Ja-Wort". Other titles work correctly and turn from black to red, for example "Mini Schlagzeug in Action". What have I to do that all titles in the posts turn correctly to red if I point on them with my mouse? Kind regards Thomas
