caption: The image shows a portrait of a woman in a green dress and hat, painted by Jan van Eyck. The woman is standing in a dark background, her face illuminated by the light of the painting. Her dress is a deep green color, and her hat is a lighter shade of green. She has a gentle expression on her face, her hands clasped in front of her. Her hair is pulled back in a neat bun, and she is wearing a delicate necklace.
