If you have a nice, linear shade across the screen from 0 intensity green to 255 intensity green, it'll appear nice and smooth with no visible banding. Now try it with light beige to light grey -- there's lots of banding. For a perfectly images, you need somewhere between 30 and 36 bits per pixel. -- ___ . . . . . + . . o _|___|_ + . + . + . .
