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.
