I am making this post in case the eye color change on the PTR is not a bug.
I found on the PTR today that they changed the color of the night warrior eyes. The old version was much more blue, where as the new version is almost completely black.
I vastly preferred the blue version of the eye color that existed previously. It was very brilliant, striking, and really got me excited when i first saw it. I do not like the black version nearly as much.
Currently night elves have some of the fewest eye customization options in Shadowlands. Adding both the black and blue versions of these eyes would be a vastly superior option to replacing the blue version with the black version.
I really hope this feedback is seen as myself and many other players (such as those commenting on the wowhead article reporting on this) want to see both options available to players.
