Hello! I was wondering if this was possible as I have 10 of these chips laying around in my workbench

Hi! As far as I'm aware, that's not possible, as color definition is limited by memory (and presumably pin flip speeds), plus that PCF8574 seems to use I2C to communicate with the Arduino, making pin flips even slower.
