When someone says they "
saw blue" when referring to Guitar Hero, it's usually to the song Jordan by
Buckethead. When on Expert, at around 60% of the song, a blue
starpower note comes up and it's easy to get. Many people agree that after this part of the song, the rest is easy to complete.
"I was just about done with the main
solo of
Jordan, and I saw blue, but I failed before I got to the
note."
