I need some help with finding palettes for my game.

I don't know what this is, so I cant decide


Edit: I get it now, One problem is there is no 100% accurate pallete for any of these, and the colour changes darasticaly all the time when it comes to Nes especially.

Well, is there a palette that is extremely trusted for both NES and SNES? (Maybe every single color that the system can use in (a) game(s))?

Opening the games and recording myself playing the games is gonna be hard cause I need to physically look at every pixel in the game and go to places like secrets or something (Yoshi's Island and Super Mario World is going to be actual torture).
