In Brune à la robe noire et jaune, we see a woman dressed in a striking black and yellow dress. The colors are bold and vibrant, creating a lively contrast. The figure is positioned against a soft, indistinct background that enhances her presence.

Her expression is calm, inviting the viewer to ponder her thoughts. The painting is executed in oil on canvas, typical of Louis Valtat's style. The brushwork is loose and expressive, characteristic of the Post-Impressionist movement. The use of color is particularly notable, with the black and yellow dress drawing the eye.

The dimensions of the work are approximately 65 x 81 cm. Louis Valtat was a French painter associated with the Post-Impressionist movement. He often focused on the female figure, capturing their essence through color and form. This particular work reflects his interest in bold colors and modern subjects.

Interestingly, Valtat was also influenced by Japanese art, which is evident in his use of flat areas of color.
