When we think of concrete, the color gray generally comes to mind. The traditional mixture of concrete, which comprises cement, gravel, sand, and water may vary in color depending on elements and admixtures but naturally varies from light to dark gray. However, compounds that add pigment to the mixture are becoming increasingly prevalent and popular,  as they infuse the concrete with hues more stable than paint. These shades result from the addition of oxides:  yellow, red and their derivations (eg. brown) are obtained with the addition of iron oxide; chromium and cobalt oxide create the greens and blues, respectively. For black concrete, it is common to use black iron oxide and carbon oxide combined with pozzolanic cement.

Minimalism has shaped architecture for over a century. Embracing new materials and rejecting ornament, the modernist movement grounded minimalist architecture through rational use and function. Throughout the 20th century, architects returned to minimalism as they worked with glass, steel and reinforced concrete. Over time, minimalist and modernist designs became more closely tied to cost, construction and aesthetic.

Just as the colors of an abstract painting or photograph can produce a certain mood, so can the colors of a building or room profoundly influence how the people using it feel. Physiologically, study after study has shown that blue light slows the production of melatonin, keeping people more alert or awake even at night. Psychologically, people associate certain colors with certain feelings due to cultural symbols and lived experiences – for example, they might perceive the color red as menacing or frightening because of its connection to blood.

Altogether, the way a room is colored can have complex effects on how its users feel, while a façade can be perceived in dramatically different ways depending on how it is colored. Below, we summarize the emotional associations of every color, assessing their differing effects as each is used in architectural space.
