The Master Sword's legend was separately established prior to legends about the hero. But if we break down the games prior to Wind Waker when the "green clothes worn by the hero" thing was first stated:
>Zelda 1 has hardly any people in general and no master sword
>Zelda 2 really is entirely done in a green tunic with a regular sword
>Link to the Past has the Master Sword but not a hero legend and the tunics are lategame
>OoT doesn't have a hero legend and the tunics are only worn by adult Link, thus nullified at the end (and if you want to go with the timeline split stuff then he still would've met all relevant parties wearing green first)
>Link's Awakening was a dream and the color tunics weren't real anyway
The hero wore green as far as the majority of people who met him would say. The people who might've seen him wearing the other tunics still saw him in green first.
