Bryan,

As I mention before, my daughter has other modern day colouring-in
type programs running on Windows XP, and they only have a pallete of
about 16 colours. I figure if its good enough for modern-day programs,
its good enough for me.   :-)

I know that it is technically possible to push the SHR screen to use a
different palette per scan line (i.e. 3200 colour images), I just
don't believe that it necessary for a kids colouring-in program. At
present, all the images are created using the default 16 colour
palette (otherwise the pallete would be different for each image) and
the program simply uses the palette info stored with the images.

I could look at tailoring the palette used in the program if people
think the colours provided aren't adequate enough, but I don't want to
have to go with more than 16 colours. It just increases the complexity
of the program both for me to be able to program it, and to the kids
who would then have a multitude of colours to choose from.

I will be releasing the source code soon, so feel free to enhance it
to use more than 16 colours if you would like to see this
feature.   ;-)

cheers,
Mike
