Applications for fluorescent pigments

The other day I visited an exhibition of paintings in an art gallery. It was not too well lit, and one painting stood out immediately because of a small but extremely brightly coloured area on it. As I went closer I saw that the bright area was painted with a daylight fluorescent colour which was applied over a white background. The artist stood nearby, but I did not have the heart to tell him that, if he ever became famous, his fame would outlast the bright fluorescent area in his painting.
