You may have heard that the Mac II can display 16 colors from
a palette of over 16 million.  It is those 16 million colors
that you see when you play with the Color Picker color wheel.
But once you choose a color the color is returned to the
program that asked for the color (the Kolor cdev in this
case), and it is up to that program to make sure that ACTUAL
color is available (i.e. one of your 16).  But that may not be
appropriate, and it's not in the case of the Kolor cdev
because it would mess up other programs that needed the color
that your chosen color replaced.

So instead Kolor just gives you the nearest color which is
currently available.  This effect is much less noticeable if
you purchased the video expansion kit because with 256 colors
active at once you generally have at least one that is pretty
close to the one you chose.  So save up those pennies! :-)
