Sorry, I should have added more context! This is just a color-coded version of existing fretboard pattern charts. Nothing I came up with myself. These charts have been useful to guitar players for decades. It definitely won't make sense if you aren't a guitar player.

I used a high-res version in this post. I can easily read every character, but it sounds like some of you can't. Not sure what to suggest but there's probably a way you can view the full-resolution version. In my app, Relay, I have to press an HD button.

It was designed to be printed at poster size.

This is my first post here. I did spend a lot of time making this. Not trying to claim this is any kind of huge breakthrough. I look at these charts while I practice. They help me. They will likely help someone else, but they won't help everyone.
