An 80A filter will be good for standard tungsten light bulbs. An 80D will be good for most fluorescent bulbs, but it won't correct for the green color, so add CC10M and CC20M filters to your kit. You won't need both CC filters at the same time for most fluorescent bulbs, but some may need it. Take test shots under the conditions you experience most and see what works best for you. There are other filters you can use that fill in the gaps between the light blue (82 filter) and dark blue (80A filter), so you can make small adjustments if needed, but the two I mentioned earlier will get you started.
