De Stijl, or "The Style," was a group of Dutch artists and well as a journal they published from 1917 until 1931. They sought to express a utopian ideal through abstraction, a fundamental reality rather than emotions. They simplified shape and color to their most basic, clearly defined forms. They worked with planes on a white background, adding only primary colors: red, yellow, and blue. Symmetry was avoided; balance and harmony were achieved through opposition.
