There is no Architecture Without Color

In 1924, Gerrit Rietveld, a Dutch cabinet-maker, left his mark on the world of architecture by designing a radical modern house in bold colors. It is an ingenious composition of colored planes that create rooms and spaces.Rietveld Schroeder
Looking at the Rietveld-Schroeder house today, it is hard to imagine that is nearly a 100 years old. Part of Rietveld's genius was his understanding of the role of color in architecture. He said:

"Light that doesn't meet any surface, is invisible. Material is visible only by virtue of its borders. The border, then, is where the material ends. There is no material without color. There's no color that doesn't depend on the chemical properties of the material. And space is invisible without borders."

This implies that there is no architecture without color. Which then means that color is not just a superficial addition to the architecture. Instead it IS architecture. You cannot separate the color from the architecture.

Rietveld went on to make many more great designs, among others the Van Gogh Museum in Amsterdam. He is now regarded as one of the greatest Dutch architects and designers of all time.
