Cloneamental, Autonav in sidebar, what .less files?

Permalink
Hi,

I've put an autonav block in the sidebar with subpages. But I would like to change the font and colors, and I can't figure out what .less files that are used for this.
I'm using the Cloneamental theme. I feel like I've tried everything, but can still not get it right.

Hope to get some help with this. Thank you.
