My day 1 project was about an analogy between retro video games and printmaking.
The Nintendo Entertainment System has a limited palette: of fifty-odd possible colors, only twenty-five can appear at any one time, and only four of those can be used in a single sprite. Games produced for the NES made careful use of this palette, expressing as much information through color as possible. This is famously the case in the Mega Man games for the NES, in which Mega Man (our hero) changes colors to indicate which weapon he’s using.
