Interesting but mixing up infrared, visible and uv is bound to lead to unpredictable and uncorrectable color anomalies in certain if not all subjects.

Before a IR 486 filter on a Leica M8 digi-cam. These dark clothing items are all black to the eye. Left to right. Pinkish wall, grey/white t-shirt, black leather belt, black pants, black polyp. t-shirt, greenish wall column black polyp. jacket, 2 grey cards, Naugahyde bag, couple of black t-shirts, dark blue dvd case. Totally uncorrectable from IR pollution from incandescent light. Everything renders well except quite a few synthetic fabric blacks. If you look very closely at many black clothes, they are actually very very dark magenta. This was a marketing nightmare for Leica, and any wedding photographers!
