That picture is extremely confusing. Colorblind pico noobs: there is no way to get actual CGA colors, just use these Pico8 approximations
0 light: (0, 8, 11, 10)
0 dark: (0, 2, 3, 4)
1 light: (0, 14, 12, 7) or (0, 14, 15, 7)
1 dark: (0, 2, 13, 6) or (0, 2, 3, 6)
Edit: I made a thing as I poke at Pico8 to see each of the 6 potential palettes: https://www.lexaloffle.com/bbs...
