How to change responsive menu colors

Using catch everest pro.  Site = lacostafilmfestival.org I have used the theme options to change the menu text color and background.  The text is black and the background is white, with a blue background for the active menu.  ** However - for the responsive menu, the coloring is not good for the active menu.  Is there a way to change the colors (text, active background, hover background) for the responsive menu? Thanks
