I hate to burst your bubble, but HAM8 is 8 bits per pixel. (Hence the
name HAM8) 6 of those bits are for the base colors (64) and the other
2 bits are the HAM modifier control bits. If HAM8 was based on 256
base colors you would still need more bits to control the 'Modify'
part of 'Hold and Modify' and it wouldn't be HAM8 any more, it would
be HAM10 or HAM12. Since you only have 64 base colors in a HAM8
image you will still get slight fringing on some color combos that
you wouldn't get on true 24 bit. If you want to see this for
yourself and you have access to an AGA machine and DPaint, go into
the pallet requester and make all of the base colors shades of grey.
Then select a bright red color from the HAM colors. Fill the screen
with white and put a red pixel anywhere on the screen and you'll see
fringing if you use magnify.
Don't take my word for it. HAM8 has been explained in almost every
magazine that has done a review of the 1200 or 4000 and any Commodore tech
support person shold be able to confirm this to you.
