saguaros I've tried experimenting changing the background color of sticky menu (either changing the pallete color and editing the custom css of the background-color you've written above), another page seems following along whatever color i choose, BUT ONLY the HOME PAGE doesn't react to the color i set up.
So could you tell me where is the setting of sticky background color of the Homepage (as you said "Accidentally, the template has style for the background of sticky section"), since it (homepage) seems doesn't affected by any color change that i've tried, maybe i could change the color through another way?
Note: superadmin account still available if you want to enter again
thank you @saguaros
