finally found the address in the MEMORY VIEWER that nobody brought up until now, thanks to pinkupi13.
i thought i was supposed to be using the Search tab cuz i was trying to FIND this address, it made the most sense to me at least.
(now if only i knew what to do from here in terms of figuring out where the hell the RGB values could possibly be, all i can figure is that they are "around that area")
although i recently found out somebody has already been working on making the colorizer work in all parts of Splatoon including the amiibo concert im trying to mess with, so maybe it'd be better if i just waited?
