Touring concert lighting designer here (when I'm not coding for money, anyway).
The above is absolutely right; LEDs produce a fairly narrow range of colors. If you look at a spectrograph of an incandescent light bulb (including halogen, which is a bit less yellow), you'll see a fairly flat curve that's a bit higher at the red-yellow (and infrared) end and a bit lower at the blue-violet end. If you look at a spectrograph of an LED, you'll see several narrow spikes. If you illuminate objects with LEDs, you'll find that certain colors appear almost cartoonishly vivid, while others that might look similar under incandescent or sunlight appear very dull.
An increasing number of small-medium concert venues are switching to lighting that's primarily LED-based, which I find very frustrating since there's not much I can do about the problems it creates. If all the LEDs had the same spectrographs, I could probably convince the performers to wear things that look good under LED light. They don't, of course.
