Key Insights

  • Color psychology, the study of how colors trigger thoughts, emotions, and behaviors, plays a pivotal role in interior design, enabling designers to create specific moods and atmospheres.
  • A career in color psychology often blends a background in psychology with design training. Some of the relevant degrees include psychology, behavioral science, or cognitive science paired with interior design, visual arts, or architecture.
  • Influential figures in color psychology include Faber-Biren, who consulted on color schemes for offices, hospitals, and the military, and Angela Wright, who developed the color effect system linking colors with personality types.

Color psychology is the study of how colors influence our thoughts, emotions, and behaviors. Even when we think we are choosing color purely for style, color is still doing quiet work in the background. It can change how a space feels, how long someone wants to stay there, and even how they behave while they are in it.

In interior design, color psychology helps turn “I like this color” into “This color supports the purpose of the room.” Instead of selecting colors based only on aesthetics, designers use color to shape mood, comfort, energy, and focus in a way that feels intentional.

Why Color Psychology Matters in Interior Design

Color can influence the emotional tone of a space before anyone reads a sign, sits down, or speaks. That is why it is one of the most powerful tools in interior design.

  • Calm: colors can help a space feel restful and grounded.
  • Energy: certain hues can make an environment feel more active and stimulating.
  • Focus: color choices can reduce visual noise and support concentration.
  • Behavior and interaction: color can affect how people move through a space and how they use it.

When designers understand these responses, color becomes more than decoration. It becomes a design strategy.

Using Color Intentionally, Not Just Beautifully

A room can look polished and still feel wrong if the colors do not match the function of the space. Color psychology adds a second layer to decision-making: not just “Does this work visually?” but also “How will this make people feel?”

That shift is what separates purely aesthetic palettes from palettes that support real-world experience.

Color Psychology As a Career Path

Color psychology can also become a specialty. Many professionals build expertise in this area by combining design training with a background in how people think, feel, and respond to environments.

Common educational paths often include:

  • Psychology, behavioral science, or cognitive science (to understand human response)
  • Interior design, visual arts, or architecture (to apply that understanding in real spaces)

This blend helps professionals connect design choices to measurable human outcomes, which is especially valuable in environments like healthcare, education, and workplace design.

Key Figures in Applied Color Psychology

Color psychology has been shaped by thinkers and researchers who focused on how color affects human experience in practical settings, not just in theory.

Faber Biren

Faber Biren is often considered a foundational figure in applied color psychology. Throughout the 20th century, he wrote extensively about how color impacts human behavior, particularly in architecture, interiors, and industrial environments. His work influenced real-world applications, including color planning for hospitals, offices, and even military use, with the goal of supporting well-being and productivity.

Some of his well-known titles include Color Psychology and Color Therapy and Color and Human Response.

Angela Wright

Angela Wright is a British color psychologist known for developing the Color Affects System, which connects color preferences and responses to personality types. Her approach blends psychology, color theory, and practical application, making it useful across industries where emotional response matters.

Her work is often referenced in areas like branding and marketing, and it can also be applied to interiors and any environment where mood and perception influence decision-making.

Kurt Goldstein

Kurt Goldstein was a neurologist and psychologist whose research explored how color influences perception and psychological response. His findings suggested that certain colors can trigger measurable reactions, including the idea that red can stimulate the nervous system while blue tends to feel calming. This type of research has influenced color decisions in spaces where emotional response is especially important such as healthcare and education.

Color As Communication

Color psychology is ultimately about communication. Color says something before words do, and it influences people whether they notice it or not. This idea is captured beautifully in a quote from Georgia O’Keeffe:

I found I could say things with color and shapes that I couldn't say any other way.

That is the heart of color psychology in design. Color is a language, and designers use it to shape experiences that feel meaningful, supportive, and aligned with the purpose of a space.
