Hold-And-Modify, also known as HAM, is a display mode for the Amiga to support the full range of 4096 colors.

Notes Edit

  • Although it supports all 4096 colors, it may need two intermediate pixels to guarantee a pixel change.
  • Under HAM6, the following possible combinations may be used:
    • Set: Use 4 bits of data to choose a color from the palette of 16 colors.
    • Modify Red: Use 4 bits to set the red pixel.
    • Modify Green: Use 4 bits to set the red pixel.
    • Modify Blue: Use 4 bits to set the red pixel.
  • HAM is replaced by True Color on more modern systems.
