Help for finding a tutorial.

Hi everyone! A few weeks ago, I saw a reel of a guy who introduced a new approach to learning guitar. He used colors on the fretboard and had a new website—it was really cool and informative. Unfortunately, I didn’t bookmark his website or save the reel. Does anyone know what I’m talking about or can help me track it down? (It's not PowMusic or Mike George) Thanks in advance.
