This story has been told here before, but this seemed like an appropriate time to repeat it.
Back in 2004 or so a bunch of us were at at tradeshow (I think it was CEDIA) and got tickets to a presentation by TI of National Treasure on a Digital Cinema DLP. Before the presentation a representative got up and told us about how many millions of colors the projector could do, so if we thought there was a color we couldn't see because of the projector we were wrong. Curt Palme instantly yelled out, "BLACK!!!". The lady may not have gotten it, but we all laughed.
