Many Arcane fans have wondered: why are Jinx’s eyes pink? As a child, she had blue eyes — just like her sister Vi. The change in eye color is not just a stylistic choice, but an important part of the show’s visual language.
It’s believed that Jinx’s eyes turned pink after an injection of Shimmer — an unstable substance that enhances physical abilities but destroys the mind. Following trauma, loss, and betrayal, Jinx fully shed her childhood identity of Powder and became the character viewers now recognize. The pink eyes symbolize that transformation.

The pink color also highlights Jinx’s instability. Her gaze literally 'burns' when she experiences intense emotions or uses her power — for example, in battle.
This effect has become a signature element of her image: bright, unsettling, unforgettable. In this way, the pink eyes are not just a design element, but a visual mark of the growing madness and strength that have become her new identity.
