If someone activates nature's way and targets a colorless eldrazi to deal its damage to target creature who has a equipment card attached that gives it protection from green. Does the damage still go through as the colorless creature is the source of the damage
You don't "activate" Nature's Way; you cast it. And, while casting it, you need to declare 2 targets: your own creature and the creature it will deal damage to. Since part of what protection prevents is targeting, you cannot target their Pro-Green creature with Nature's Way. While it is true that the damage would be dealt by a colorless source, the game never gets to that point since Nature's Way can't target their creature to begin with.
