Lyte, my knowledge is theoretical from the degree I'm taking rather than from experience, but yes. Apparently darker mulches will help absorb heat and warm the ground (so good in cooler climates), whilst lighter ones will cool the ground (better in warmer climates; some plants' roots do not like too much warmth) - and reflect light back up to plants helping their photosynthesis. At night, black mulches will allow heat to escape faster, whilst lighter mulches will retain heat better. Its horses for courses as to what is best for your particular situation.
