To be fair, the way Woz did color on the ][ was pretty wild, but unfortunate they weren't able to properly copy that as well...
They were able to get color working on the subsequent 1200 model. And I believe color was accessable via an expansion card, I didnt want to be staring at a tv at short distances so I was content to game in monochrome.
Screens were low enough resolution back then that you could look closely at the screen to see how he got the six hires colors.
