In Composition in White, Red, and Yellow, vibrant blocks of color dominate the canvas. The painting features a balanced arrangement of white, red, and yellow rectangles. These geometric forms are outlined by bold black lines, creating a sense of structure.

The overall composition is both dynamic and harmonious, reflecting Mondrian's commitment to abstraction. The painting is executed in oil on canvas, a medium that allows for rich color application. Mondrian employs a grid-like structure, which is characteristic of his later works. The use of primary colors, along with black and white, emphasizes the purity of the forms.

Viewers can appreciate the precision in the placement of each rectangle, which contributes to the overall balance. Piet Mondrian was a key figure in the development of abstract art, particularly through his involvement in the De Stijl movement. This work, created in the 1930s, exemplifies his mature style, focusing on simplicity and clarity. An interesting fact about this painting is that it reflects Mondrian's belief in the spiritual qualities of color and form.

He aimed to express universal harmony through his art.
