“Color is life; for a world without color appears to us dead.” Distinguished painter Johannes Itten described with these words the exceptional power of color in our perception of the world. As a sensory event, color not only defines what we see, but also how we feel and think; it has been shown to alter productivity, inspire decision-making, shape our perspective, and influence our well-being. Especially in architecture, these effects materialize and reach their maximum splendor. Design is, after all, a visual form of communication, and color palettes –coupled with light, shadow, texture and sheen– play a critical role in conveying a building’s message. They create the ambiance that supports the function of a space, completely transforming user experience. Even the greats have recognized this power: “Polychromy is as powerful an architectural tool as the plan and section,” Le Corbusier once said.
