Thanks. Good video. I think it's a bit advanced for me because he might be assuming that his audience already understands those chords in the context of a musical progression. Unfortunately, I don't . I also think those chords sound great standing on their own, but they also get their colors from their place within a progression. Anyway, this video also helped me get a sense of chord color. It discusses chord inversion from a much simpler foundation, but I think it complements your video.
