How can I change the 'Sale' element color without affecting the background?

No, the overflow background on mobile is consistently displaying in green, aligning with the color assigned to the ‘Sale’ element (designated as ‘.color-background-2’). Despite my attempts to customize this element, it appears to be directly influencing the overall background color. When I refresh the website on a smartphone by overscrolling at the top, the overflow color is green. I urgently need a solution to ensure that the overflow background remains white while retaining the designated green color for the ‘Sale’ element.
