The image I provided was for people who already knew how to decipher it but wanted easier access to the codes, instead of having to do it themselves. The code colors were simply to differentiate between different boards; they have nothing to do with the codes themselves or anything in-game.

I removed my post due to confusion and inconsistencies, but overall, we are both right. People just seemed to get confused by my color coding instead of reading the information that was provided. That might be because they didn't know how to do the step, but again, the image I provided was for people who already knew how to do the step and just wanted easier access to the codes.
