In Composition with Blue and Red, Piet Mondrian employs a bold palette of primary colors, primarily blue and red, set against a white background. The painting features a grid of black lines that create a dynamic interplay of rectangular shapes. These geometric forms are arranged in a seemingly random yet harmonious manner, inviting the viewer to explore their relationships.

The overall effect is one of balance and structure, characteristic of Mondrian's style. The painting is executed in oil on canvas, a medium that allows for vibrant color application and precise line work. Mondrian's technique involves the careful placement of color blocks, which are outlined by thick black lines. This method not only defines the shapes but also enhances the visual impact of the colors.

The dimensions of the work are approximately 60 x 60 cm, making it a compact yet striking piece. Piet Mondrian was a key figure in the development of abstract art, and Composition with Blue and Red exemplifies his commitment to geometric abstraction. Created in the 1920s, this work reflects Mondrian's belief in the spiritual qualities of color and form. An interesting fact about this piece is that it is part of a series where Mondrian explored the reduction of visual elements to their essentials.

This approach laid the groundwork for later movements such as Minimalism.
