The new OS in the Mac II introduces a "Color Quickdraw", which is
compatable with the color model of the old Quickdraw (ie, drawing on
seperate color planes), and introduces a color manager which does
all sorts of wonderful things for you.

The video board from Apple is sold with 4 bits/pixel, and with an
option added to the video board, will give you 8 bits/pixel.  With
dithering, you can create fantastic images.  And the color screen
does not flicker in any way (like the Amiga does in high res mode).
The color screen even refereshes at 66.something Hz, making it so
that it doesn't flicker noticably under flouresent lighting (like the
Sun workstations do...)
