Where do I change the color behind(?) the sticky menu
if you manually move the scroll bar you can see a static background being applied where the sticky menu is no longer as tall as the main menu..
how do I either a, get rid of this issue all together.. or b. just change the color so it is not so obvious and irritating?

Using the betheme header plugin hides the header background color
I had to disable the plugin, change the color, and re-enable the plugin
thank you
