Color palettes for Apple II

Each file contains 16 colors in RGBA format.

Palettes have been split in two folders:

  • Realistic

Palettes attempting to replicate either exact standard Apple II colors, or variations from other computers of the era (e.g. NTSC for C64 at different settings)

  • Fantasy

These do not necessarly follow standard colors or any existing computer; they will give your display a different feel and can fit some games or specific esthetics very well.

Customizing palettes

An a2p file can be created or edited with a hex editor such as HxD.

Each color is defined as four bytes (R,G,B and 00 to separate), and they must be ordered as follows:

  1. Black (Hi-Res color 0 and 3)
  2. Magenta
  3. Dark Blue
  4. Purple (Hi-Res color 2)
  5. Dark Green
  6. Gray 1 (darker)
  7. Medium Blue (Hi-Res color 6)
  8. Light Blue
  9. Brown
  10. Orange (Hi-Res color 5)
  11. Gray 2 (identical or lighter than Gray 1)
  12. Pink
  13. Green (Hi-Res color 1)
  14. Yellow
  15. Aquamarine
  16. Black (Hi-Res color 4 and 7)

The palette can be loaded from the FPGA core at any time via OSD option.
