Hamburger menu icon keeps displaying the mint green background on click!

Hey guys, I know this is probably an easy fix for this forum but i am stumped!

I have setup my header and all looks good for now but the hamburger icon keeps flashing the clashing green color when clicked, I have changed EVERY background color I could find.

I cannot see where this green setting is? I’m have to get outside help, I just can’t find it. Maybe I have to use custom code or rebuild the menu icon completely from scratch(hopefully not), I’m using the prebuilt header from the symbols choices.

Ya yesterday I fixed it. Added a second class name to the button box and changed the colour again, not sure why this worked but it did!
