24 bits = 16777216 different colours, but it's not enough -- human
eyes can make out more shades; the 3000000 figure just isn't compar-
able. 24 bits means 8 bits each for red, green and blue. 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.
