Okay, storytelling through colour.
When I picked Archlyphion's colour scheme, magenta was chosen for numerous reasons. It's mostly symbolism based on how the colour spectrum works.
Firstly, I see magenta as a mix of red and violet, which have wavelengths marking a boundary between the visible light spectrum and anything beyond human vision (infrared and ultraviolet respectively).
Secondly, magenta is an extra-spectral colour, meaning it technically does not exist in the visible colour spectrum. So in a rainbow, there's no such standalone hue like this.
This is to allude that the Maze itself is separate from the True Universe and that to them, they do not exist. Or another way to put it, it's beyond their epistemological and mortal senses they could even comprehend, due to how time and physics violate their laws of nature.
So overall, magenta is the colour of the Maze's chaotic nature.
Old infographic I made years ago just to share for this explanation, but I would definitely update it to make that more prominent.
As for the cyan/turquoise? I read up that it can represent a myriad of things in different cultures, but ones that stood out to me were truth, wisdom and the infinity. I like to call it the colour of the mortals, or those who have yet to understand the Maze (or at least try to make sense of it through their rational ways).
So if there's anything you may see with turquoise text or colour scheme, then for the most part.... that's the colour of those told only by one perspective of what they think the Maze is.
You have yet to see the rest.
