Yeah... if I see a green overdrive, I immediately think, "it must be based on the Tube Screamer." The thing is, though, many ovedrives aren't. And there are a few very recognizable overdrives in other colors like the Klon. If I see a gold pedal, I immediately think "must be going the Klon thing". Or for a Marshall in a box.
And many other very iconic pedals that are not overdrives are green and are not overdrives like Line 6 DL4 or the Boss Chorus Ensemble.
I guess I'm saying yes and no, LOL.
