Palette

Here is a comparison between Amstrad CPC palette (theric colours) and PC-6001mk2 supposed palette.

  • The palette has 15 colours and one transparency channel ink enabling to overly the computer's video over another TV video (as done with MSX1 or Thomson MO5/TO7 computers)
  • This palette is actually available on Amstrad CPC computers as it features black+grey+white, the 6 basic RGB cube colors : Red, Green, Blue, Cyan, Magenta and yellow, and cross colours : Orange, Lime, Seagreen, Mauve, Purple, Sky blue (those are CPC palette names)
  • It is quite an exotic and colorful palette, and it doesn't enable proper gradiants like most other comparable 16 ink palettes.

CPC related?

Just check the specs from the PC-6001 MK2 and the PC-6601.

Those are basically Amstrad CPCs with extra sound capability and less video modes and palette.
