Baskerville theme: navigation bar

Hi,

I have the Baskerville theme installed on my blog https://www.cranberryandapricot.com

After a recent update to the theme, it seemed to loose my colour settings. I managed to reset them all apart from the colour of the navigation bar, this also seems to be the colour of the footer. I have tried searching for the colour code it currently is to find and replace it but have had no luck.

The colour I would like to change it to is #2b3541

Could anyone tell me where the code to make these colour changes are please?

Thanks,
Ami
