In Femme assise, a seated woman is depicted in a vibrant dress, surrounded by a soft, impressionistic background. The colors are rich, with blues, greens, and warm tones blending harmoniously. The figure's relaxed pose suggests a moment of quiet contemplation.

The brushwork is loose and fluid, typical of Impressionism, creating a sense of movement and life. The painting is executed in oil on canvas, showcasing Guillaumin's characteristic style. The dimensions are approximately 65 x 81 cm, making it a medium-sized work. The use of color and light is particularly notable, with dappled sunlight illuminating the figure.

Viewers can appreciate the texture created by the thick application of paint. Armand Guillaumin was a key figure in the Impressionist movement, known for his vibrant use of color. Femme assise reflects his ability to capture the essence of his subjects with spontaneity and warmth. Interestingly, Guillaumin was also a close friend of Vincent van Gogh, and his work influenced the development of modern art.

This painting exemplifies his unique approach to portraiture.
