Bubble Calendar Button Design

I have added the bubble calendar plugin. It is amazing, and really easy to use. The issue I am having is the buttons at the top (Month, Week, Day / Next, back) are in a color that does not fit my web design. I am able to edit The color of events displayed on the calendar, though am not able to figure out how to adjust the calendar buttons. Is this possible?


was about to ask this too. can we really not customize the look of the bubble calendar?
