Jinx’s changing eye color

I saw a YouTube video where the guy said that Powder’s eye color changed after her discovery of the stones in s1e1. He mentioned how she had more gray colored eyes prior to discovery of the stone and got her blue eyes after finding them. I’m watching this scene again to try to notice this detail, and I did see her eyes blue during that moment, but they went back to their gray later. Looks like it was just the reflection of the stone glowing in her eyes that made them appear blue in that moment.

How does Jinx end up with such emerald blue eyes in adulthood? She’s the only one on the show whose eye color changes (I think). Vi’s seem to be a lil brighter in adulthood but not this dramatic change like w Jinx
