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...
Screens were low enough resolution back then that you could look closely at the screen to see how he got the six hires colors.
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.
