Alex Katz's piece titled Vivien is a striking portrait that exemplifies his minimalist approach and keen ability to capture the essence of his subjects. The artwork features a close-up view of a woman named Vivien, her face presented with simplicity and elegance against a dark, monochromatic background. Katz employs his characteristic flat colors and clean lines to highlight Vivien's facial features, focusing on the subtle nuances of her expression and the play of light and shadow on her skin.

Vivien is depicted with a calm and contemplative expression, her gaze directed slightly to the side. This pose, combined with the minimalistic rendering, lends a sense of introspection and quiet intensity to the portrait. Katz's use of bold, unmodulated color blocks emphasizes the smooth contours of Vivien's face and neck, while her understated attire and the dark background ensure that the viewer's attention remains focused on her serene expression and delicate features.

The portrait showcases Katz's mastery in distilling the human figure to its most essential elements while maintaining a strong sense of individuality and presence. Vivien's lips are painted in a soft, natural shade, and her eyes are rendered with simple yet expressive lines, capturing a moment of subtle emotion and thoughtfulness. The single earring adds a touch of elegance and serves as a focal point that enhances the portrait's refined composition.
