> It is the most technological color, and I’m willing to claim that this is why it is usually, in science fiction and elsewhere, used to represent the future.

For me it is because of red- and blueshifting[1]. Far away galaxies appear both older and redder the further away they are, so red is the past. And if you go really fast, the forward view will be bluer, so in the sense that it is where you go, blue is the future. [1] https://en.wikipedia.org/wiki/Redshift#Blueshift

That’s exactly backwards. If the galaxies are turning red, you are in the future. If you they are turning blue, you are going into the past.

An analogy is that if everyone around you is getting older, similar to red shifted galaxies, it means time is advancing forward. If everyone was getting younger, then you’re going backward in time to the past.

Red is the future.

Aren’t these statements saying the same thing?
