The highlight color may be sufficient, but I find it too slow to fade-in/fade-out. It may not be an issue if the game has a mouse cursor anyway to see what you're pointing, but if it's cursor-driven, it makes the interface look sluggish, and also reduces visibility: If you try scroll continuously down to select an item near the end, the "current" item will not be highlighted for long enough to become visible, and so you can't see anything until you release the down control.
