One thing I like about LED lighting is that in generally involves a bunch of LEDs, which means you can soften the color of the light by mixing in some reds and greens.
Good point. I once saw an orchestra and noticed the "richness" of the white lights. It wasn't until after the show I sneaked up there and saw blues and reds mixed in with the whites. I was thinking it was just the effects of the fresnel lenses on the powerful lights.
