Proposed change¶

To reverse it to the old appearance:
https://git.typo3.org/Packages/TYPO3.CMS.git/blob/refs/heads/TYPO3_8-7:/Build/Resources/Public/Sass/scaffold/_modulemenu.scss#l60
https://git.typo3.org/Packages/TYPO3.CMS.git/blob/refs/heads/9.5:/Build/Resources/Public/Sass/scaffold/_modulemenu.scss#l60

Current color code

    .modulemenu-item.active {
        .modulemenu-item-link {
            background-color: rgba(0, 0, 0, 0.15);
        }
    }

Adjusted color code

    .modulemenu-item.active {
        .modulemenu-item-link {
            background-color: rgba(255, 255, 255, 0.15);
        }
