Do you think color would take a while to get used to changes? Either a big or small one
Yes, I do. Not only because he’s Autistic, already struggling with change and needing routine and structure since he was young, but because of the Void. He spent the better half of two decades of his life in the Void, able to do very little. The only changes came from Color, Gaster, and from within themselves.
In this type of understimulating, predictable environment, you get used to it—it’s literally just your way of life now—and it’s extremely hard to adjust to anything else outside of it; which is why i think Color started developing routines and habits in the Void that still stick with him in his new life.
That being said, however, I think it’s also precisely because of the Void that Color can’t stand anything being the same for too long anymore. He can’t stand the mind breaking boredom, the same things every day, nothing ever changing at all. The quiet and the predictability.
He can’t stand staying in one spot or area for too long, even if that’s what he often finds himself doing when he needs comfort or something familiar in a world that isn’t familiar to him anymore. Inevitably, however, he will want to move away from this spot or area the second it starts reminding him too much of his time in the Void; getting paranoid, restless and irritated.
Which is why he travels around a lot, moving from AU to AU. One of the many reasons why he probably can’t hold down a steady, full time job either. He’s definitely still a nomad, still full of wanderlust—not wanting to miss out and not appreciate what he’s been given the chance to have again.
But he still needs something familiar amongst all the new and change—he still needs a structure, a routine, of sorts. Probably something he does the exact same way every single time before he gets ready to move somewhere else—even if as simple as always packing his bags in a certain order. Or always calling Delta and Epic at a certain time of the day.
