Gridmarket Sidebar Arrow Color

I just figured out how to install Gridmarket. I really like the way my products are displayed now.

In the sidebare, the Categories and Popular Products have green arrows pointing to them. Is there a way to remove the arrows or change their color?

Many thanks to all of you who write the code that makes my web site sing.
