Purple is generally void, blue is generally arcane. Blood elves are getting blue eyes because the Sunwell is a light infused arcane well. They don’t really have any connection to the void.
I don’t even think void elves are getting purple eyes, pretty sure they’re NPC only.
Green came from being around fel energy. Blue came from the arcane in the Sunwell. I don’t recall blood elves with purple eyes. Yellow eyes come from the Sunwell being light infused.
I recall another topic done to death and it finally happened. So while we are discussing customization for races, we might as well ask for several options that are canon in-universe as well
I really want them, because I could use them on my warrior and mage. And they fit in with the Belf armor and Venthyr stuff. I’ve been wanting San’layn or Dark Ranger type customizations.
The Blood Elf fel green and the holy glow sure. High Elves before then had different colored eyes not just blue. They where all given blue eyes in game for in game reasons. Look it up.
