Eye Color in Literature, Significance of, Semiotic Meaning

I feel sorry for novelists when they have to mention women’s eyes, there’s so little choice . . .
Her eyes are blue: innocence and honesty.
Her eyes are black: passion and depth.
Her eyes are green: wildness and jealousy.
Her eyes are brown: reliability and common sense.
Her eyes are violet: the novel is by Raymond Chandler.

Flaubert’s Parrot
Julian Barnes
