I have a great categories sidebox, but I cannot figure out how to change the rollover colours. It's got to be in the code somewhere, but I've looked and looked and cannot find it. I downloaded the Firefox Web Developer Tool, but I'm obviously not using it right because it's been no help to me.

The site is here: ellybooks.co.uk/shop

When my cursor moves across the category sidebox on the left, the main catories turn light blue. The sub categories turn pink. Where is the code to change this?

How do I change any of the background colours in this sidebox?

If someone could find out which file and which line of code, I would appreciate it. I've changed other colours in my template, but this one's got me m totally stumped. I need a bit of hand-holding.

Many thanks
