I assume you mean one million POSSIBLE colors.
One million colors is not excessive, in fact, it seems sad that they would
get SO close to state of the art, and come up short.  Sorry, state of the 
art is 10 bits output PER GUN, or 30 bits total (one billion possible colors.)
I guess I should say that they came so close to the standard 24 bits (16
million colors), and came up short.

Now one million translates to 20 output bits.  Notice that 20 doesn't 
divide by 3, so what's it going to be: 7 to red, 7 to green and 6 to blue?
Poor blue, it always looses.

One could argue that you can't see the difference, maybe you can't between
1 and 16 million possible colors.  Its just that (8,8,8) is so much cleaner
than (7,7,6) or whatever it will be.

(Note:  this is not an Amiga Flame.  
Just a computer graphics architecture flame.)
