#I couldn't tell if Ciri has green or blue eyes so I quoted both

[kattahj]

“[G]reen eyes always entail TALENT, usually for MAGIC but sometimes for MUSIC [...] blue eyes are always GOOD, the bluer the more Good present; and then there are violet and golden eyes. People with violet eyes are often of Royal blood and, if not, always live uncomfortably interesting lives. People with golden eyes just live uncomfortably interesting lives and most of them are rather fey into the bargain. Both these types should be avoided by anyone who only wants a quiet life.”
