the same thing as xenon. Both are much bluer (5000 degrees Kelvin
roughly) than incandescent -- usually about 2900 degrees Kelvin).

I've never met a projectionist who used a filter (an 85 would work)
to balance arc or Xenon to be close to incandescent -- it's not a
common thing, except perhaps in a lab screening room. Most people
just live with the fact the print will appear blue, but the
audiences' eyes will compensate pretty quickly. The eyes tend to see
white as white, whether it's bluish or reddish, as long as there's no
