2D panels and nighttime graphics

What is the strategy for nighttime panel views? Should I just test for the A:Nighttime(?) parameter and panel lights state, and use an appropriate bitmap? (Talking strictly 2D here) What about the dreaded Pink Haze (and way does it change the color of my luminous radio digits?), can it/should it be turned off? Any tips/hints appreciated!(OK, I know; two questions in one day, but the first was an easy one...)Douglas
