TYPO3 Core

Relevant places in source:

typo3/sysext/t3skin/Resources/Public/Css/visual/element_csm.css
15:table.typo3-CSM tr.typo3-CSM-itemRow {

typo3/sysext/backend/Classes/ClickMenu/ClickMenu.php
1192: <tr class="typo3-CSM-itemRow" onclick="' . htmlspecialchars($onClick) . '" onmouseover="this.bgColor=\'' . $GLOBALS['TBE_TEMPLATE']->bgColor5 . '\';" onmouseout="this.bgColor=\'\';"' . $CSM . '>

Currently the color-values are set in $GLOBALS['TBE_STYLES'] and are afaik not yet available via CSS. So for the moment they can't be used with CSS-classes or so.

As a general solution for the hovering in ClickMenu I see the using of CSS-hover-states. But to be able to add colors in a central place in the CSS maybe we'd need to use SASS or the like then.
