How to change BeTheme Action Bar link colour

I'm using BeTheme Renovate theme and the Action Bar at the very top is using dark blue colour links, which is difficult to read on a dark gray/black background. I inserted HTML code to it in BeTheme Option but it doesn't change it properly, i guess I need to change it in CSS, preferably in Child Theme Editor. I would like to change it from dark blue to just white colour. Can you please assist with this.

Thanks
