I read an article a while back (before the PW was even announced) that talked about the light hues coming from clear LEDs. A clear LED normally has a blue hue I think. To get warmer hues like yellow or pink or tan they coat them with some chemical. This is probably fine for flashlights and such but I'm wondering if this coating on the LEDs is rather uneven in thickness and distribution and can therefore cast weird shadows with different hues?
