TV-MOVIES
Yennefer is played by Anya Chalotra on the show, and like Yennefer of the books, Chalotra has long black hair and wears contact lenses to match the sorceress's violet eyes. The video game Yennefer appears to be some years older than Chalotra but age doesn't mean much when you are practically immortal.
In Season 1 of "The Witcher," Triss has shoulder-length, curly brown hair which is actually more accurate to the character of Triss in the novels. However, Triss in the video games is a very striking redhead which is probably why Triss’ hair in Season 2 is tinted red.
