Maps like Love like Woe and Jump out of your Car used combo colours taken from the BG very effectively. If you could choose combo colours from the BG with a droppper it would make this easier
There is of course the potential problem with the colours blending with the BG if the mapper uses it badly, but that should be filtered out as the map gets modded.
