- Because 16-bit modes has only 5-bits (32 colors) of RGB,
- Ham8 has 8-bits (256 colors).
- For a number of graphic-styles this is better.

- There is no dithering involved in ham.

- Check your facts. Ham8 is for all practical reasons limited
- to 262,000 colors on screen at once with, one-pixel changes.
