Yeah, i get that some chords give bad experiance, I myself hear over the top when things are the slightest bit out, even one string off a couple cents really grates on me, and i get odd/bad lights and/or feelings from it, even when most people dont hear it. I have one friend that does hear it all the time but doesnt get the colors/lights i do, he like me also has what is called perfect pitch.
I also an also really quick to figure out or change something that isnt "correct" in things when getting all the parts together, like sometimes there is a single note that just doesnt jive with the vibe wanted in a song, i work with them the get what they want done and on tape...wich sometimes is actually pain that is wanted, so i do get that some chords are painful and sometimes that is exactly what is wanted in that specific situation.
But i also do get colors for other things too, like i "see" electronics, like wiring and electronics i really see the flow on how things will run without a schematic even when designing something, even designing networks and doing security i can see that "gaps" or places there can be issues, alway been really easy for me to do electrical type of design and alike.
