"Most races have different hues and patterns." (Source: Discord)
Lighter eyes may or may not indicate different light sensitivity. (Source: Discord)

Note: Vampires will have red eyes, regardless of what they were in life. They’re a vampire now.

** Note: Technically Purple is unknown, but “in the case of **Uruki”* - his one purple eye is due to his Lamia/Naga heritage.*

**** Note: “If they have eyes at all, of course.”*

Human Eye Colors

For humans, if they have a color in their eyes, it can both indicate their lineage and magical abilities. (Source: Discord)
Humans with any coloring other than pure grey means there was a mix with non-human somewhere in their lineage. (Source: Discord)
"When a pure human has a child with a non-pure human, that child will always have grey eyes and the bloodline will effectively be reset to pure human." (Source: Discord)
"Generally [eye colors do not skip generations]. Eye color remains consistent." (Source: Discord)

"Heterochromatic eyes are incredibly rare in all species, though more common in hybrids." (Source: Discord)
"Heterochromatic eyes are very rare, and usually are considered both an incredible gift as well as a dark omen. Those with two different colored eyes are usually born of two human hybrid parents, though human and non-human parents and two non-human parents have been documented." (Source: Discord)
"When a child is born of two different bloodlines, and possess two different eyes they inherent the traits and abilities of both bloodlines. A child with green and pink eyes (Elven and Fae) are gifted in both Illusion and Transmutation magic, and take personality traits of both sides. However, they are also treated with incredible care, as they have the potential to create entirely new species. This is how the Wendigo race was created, a union of the Daemon and Fae bloodlines by two hybrids. A child born with a black and pink eye, that eventually reached adulthood as the first Wendigo."

Uruki is currently the only known character with heterochromatic eyes.
