Chameleon

The quartz walls started to fade into a bigger opening; the clearing was spherical, like an observatory for the clouds and the sky, with small pillars of stone arranged around, mimicking nonexistent constellations.

How do you know the exact shape of all constellations but not even your name?
Meh, it's been long since the encounter with red, and white is starting to become repetitive. Not knowing yourself is just a bother, nothing much anymore.

"Long," you aren't sure, it feels... wrong.
Yeah, you lost touch with time, but you should know if it has been minutes or years, yet you can't.

Everything is still white, but something stands out in the center of the clearing, on a pedestal, it's...
It's color!

A long cylinder is placed atop the white room, colored in various shades of blue, ranging from a snow-light to a night-dark.

Maybe blue is your color, you think out loud, it's not like anything will hear you anyway.
And if it was, then which shade?

Blue is a colder color, and a very common one.
It's in the sky, even if here everything is white and black.
It's in the water too.
But there isn't much life that is colored blue, isn't it weird?

Maybe you're dark blue, like the night sky, it's a blend-in color, and also strangely calm.
The night is strangely calm.
When everything is asleep, you're left alone only with your thoughts.
Doesn't that make you think of anypony!

Yeah, dark blue hits too close to home, maybe it would be best to take a break from "alone."

What about light blue? It isn't the night...
No, light blue is the sky, the winter, the cold.
You don't feel like you're someone cold. If you think about it, you don't feel anything at all!
This place seems to have gotten you numb.
How long has it been anyway? It's hard to say when nothing gets affected by the outside. Everything is monochrome, the sky is fixated above, and the walls are all the same.

But Rainbow Dash is blue, and she doesn't feel bland.
Maybe you need to get more colors?

Just when you thought you were done with those existential crises, here they come again, galloping!
Maybe you should do like your problems and just try to run away.

Blue wasn't your color anyway.
