The original QD actually supported only 8 colors in 3 bit planes, period.
The new QD software supports 2^48 possible colors. The current hardware
allows 2^24 distinct colors of those to be used.
Depending on the color card, colors can be implemented through bit planes,
or through a 'chunky' scheme (if bit planes are vertical, then chunky are
horizontal arrangements of the bits corresponding to a pixel.) The
current Apple and SuperMac* cards offer up to 8 bits per pixel, which
allows any 256 colors of the 2^24 colors supported by the card to be displayed.
* Thanks, Larry.
