COLOR FOR ACCORDIAN / HAMBURGER MENU IN SPIRIT

Hi - I have the Spirit theme and I changed the theme colors site-wide with no changes at the page level. I tried to get an answer to this question in the live chat but couldn't get it figured out. All colors changed with no problem except the vertical menu background / dropdown from hamburger. The background is still that moss green color which is not anywhere else in my theme and it looks horrible. I tried to find the object in CSS to edit but I can't seem to locate it. My site is password protected but if you want to take a look at it the password is @Liberty. The site is libertygroupbenefits.net. Any help is much appreciated! JO
