I am fairly sure that blueprint generation generates a blue box block which is changed to a random unfound/ungenerated blueprint upon player proximity.Nope
If this is not the case, Then why do blue boxes spawn in converted DD worlds that I haven't explored?
It was the first biomolecule that was able to survive and evolve with the atmosphere within (ancient) plants.Why is it's molecular structure such that it is a poor absorber of green light?
Because, Gaia's favourite colours are green and blue. So her natural bias made her make chlorophyll reflect green light, And the nitrogen in our atmosphere scatter blue light.
