What hair color does Triss Merigold have in the Witcher books?

Unfortunately I have never read the Witcher books and I'm interested in the original appearance of "Triss Merigold".

In the Netflix series the hair is brown and in the game the hair is red.

In the books her hair color is chestnut brown, a brown with a reddish note.

Thank you 🙂

In Witcher 1, she has the right hair color as in the books, auburn. In Witcher 2, she suddenly had red hair, which was then adopted in Witcher 3. In the series, the hair color is also incorrect, far too dark.

The eye color is also wrong, by the way. According to the books it should be cornflower blue, in Witcher 3 it is a light green, in the series it should be brown.
