Summary

Q.What are the different 'souls' in Undertale?

A.Undertale distinguishes human SOULs (upright, colored hearts) and monster SOULs (inverted white hearts). The game shows seven human SOUL colors—commonly linked to specific traits—and the player’s red SOUL is tied to the game’s SAVE/Determination mechanics but its exact “trait” is debated.

In Undertale, “SOULs” come in two main types: human SOULs (upright colored hearts) and monster SOULs (inverted white hearts). The game presents seven distinct human SOUL colors that fans and in-game text associate with traits; these are most often listed as:

  • Cyan — Patience
  • Orange — Bravery
  • Blue — Integrity
  • Purple — Perseverance
  • Green — Kindness
  • Yellow — Justice
  • Red — (player’s heart, commonly associated with Determination but not explicitly labeled in-game)

The Snowdin “Ball Game” and the coffins/flags in the game are the primary in‑game sources that name those traits and map them to colors, while fights (Papyrus, Undyne, Muffet, Mettaton, etc.) show mechanics that change your heart color during battle. The concept of Determination (what lets humans SAVE/LOAD) is explained in the True Lab and SAVE Point entries and is often shown as a golden/yellow motif in the game; whether red itself is canonically “Determination” is a matter of interpretation and fandom debate. For the in‑game trait mapping see the Snowdin Ball Game and the Eight Humans entries, and for Determination mechanics see the Determination page. (undertale.wiki)
