So By Now You've All Probably Seen The Fanart Where Killer Wears Some Hot Black Clothing.

So by now you've all probably seen the fanart where killer wears some hot black clothing.

I drew it as a kitty!

My undertale soul colour headcanons

-Monsters have soul traits as well, but they are too desaturated to be visible. Determination is not a soul trait but a substance that saturates the colour of the soul. Humans, who have a lot of DT, have very bright soul colours.

-A human's eye colour matches their soul's. Since Chara/Frisk (Depending on who you think was to blame for the red eye colours in the soulless pacifist run), have red eyes, and eyes are the window to the soul after all.

-Hot take: If Sans had a soul trait, it would be Justice, not Patience

Most fanworks associate Sans with patience, but if you think about it not much about him relates to the trait. We give him that because he's blue, lazy, and doesn't do anything. But that's not really patience, just laziness, and probably depression.

Sans is much more intertwined with the concept of Justice. He judges the player for every EXP they've earned. His very magic delivers karmic retribution. He fights you only on the route where you kill everyone. The yellow eye is usually skimped in favour of the cooler (ha) looking blue eye, but I personally think it has a lot more lore importance.

All the sprites from the recent newsletter! Notably we're getting some new Flowey sprites for the first time in what seems like AGES!! Have fun Flowey fans :3

"sometimes i wonder what he felt in that last moment... pain? regret? sorrow?

... relief?

it's probably best not to think about it."

What if souls with the same colour are linked in the underground?

I've always found it weird how Frisk became entangled with the first fallen human. Why is their name on our stats? (Do they gain LOVE even if our kills were not their fault?) Why do they narrate our world? Why do we hear the last thing they heard before they died, when we die? Why do the game's files seem to imply that we use their save file when saving? They're dead, right? They were awakened thanks to our determination? That doesn't explain much if I'm being honest.

This isn't really a theory, more so a thought. What if souls that are the same colour become linked to each other in this way?

So if a kindness human fell down after a neutral ending, the other (dead) kindness soul would awaken and narrate their world, their name would be on their stats, and upon death you could hear something they heard. It's a bit odd, especially when you think about multiple humans of the same soul colour falling, but I think this could make for really interesting AUs.
