the number of color display in c2

[invox]

1 from the .y64 file, i think the numer of color display in c2 is 2^^6)*(2^^4)*(2^^8)=2^^18=262144 in theory.
2 the color codes are NOT compacted code or commonly used pictures format, perhaps they are created by PYRO. i am in puzzle, why PYRO did NOT use codes format like 11112222333344441234?
3 the color display codes' format is like HSL or HSI, is a misture of grey degree(256 kinds) + basic color(64kinds), while i am not sure the mixture calcultin method of codes to get the ultimate color display.
4 i am sure that the color display mode will be cracked soon.

1) PJB had traced and cracked the color display mode in c2, the exact color number in c2 is 2^^16, while PYRO used 2^^18 colors in the game, that is a real color such as RGB(0,41,176) can be expressed by 4 codes, or averagely 4 coldes samely display 1 color.
2) PYRO used a special color display mode in c2 ,not any usually color mode.
3) i must say sorry to SICK, for i want to finished the file of 3 key files for c2 this year, while im busying.
