Technically, yes, but practically no, because none of the 16.7M
color modes have been implemented yet :(

Actually, when the SS is in 32k color mode, there are no palettes.
The color is directly represented by 5 bits of red, green, and blue 
(which is why it is sometimes called direct color).  5 bits gives
32 different values for each color, and 32^3=32768.  But still, 
displaying a 3200 color picture would be trivial.  All that needs
to be done is to translate the palette color to it's direct color
for each pixel.

I believe that SecondView will display 3200 color pictures, and 
I think that Graphic Viewer (shareware) will also do this.

: At least, not yet.  :)

Better get one while you can :)  Maybe it would actually persuade 
Sequential to get off their butts and write some stuff for it!
