The Psychology of Interior Design: How Colors and Shapes Affect Our Mood

Interior design isn’t only about creating a functional and aesthetically pleasing space. It’s also about understanding how the design elements impact our emotions, thoughts, and behaviors. One of the essential aspects of interior design is the use of colors and shapes, which is known to influence our mood.


Color is perhaps the most significant factor in creating an atmosphere in a room. Different colors are known to evoke different emotions and feelings.

The color blue is known for having a calming effect. It can lower blood pressure, decrease respiration rate, and slow down the heart rate. That’s why it’s a popular color for bedrooms and bathrooms.


The color green is also known for its calming effect, as it’s associated with nature and life. It’s believed to reduce anxiety and promote relaxation, making it a great color for living rooms and home offices.


The color red is associated with passion, love, and energy. It can stimulate the senses and increase the heart rate, making it a great color for dining rooms and entertainment areas.


The color yellow is associated with happiness, optimism, and creativity. It’s believed to stimulate the nervous system, increase energy levels, and promote concentration, making it an excellent choice for home offices and children’s rooms.


Shapes are another factor in interior design that can impact our mood. Different shapes are associated with different emotions and meanings.

Circles and Curves

Circles and curves represent softness, femininity, and unity. They can create a sense of comfort, relaxation, and calmness in a room. That’s why they’re popular in bedrooms and living rooms.

Rectangles and Squares

Rectangles and squares represent stability, balance, and strength. They create a sense of competence, dependability, and structure in a room. That’s why they’re popular in libraries and home offices.

Triangles and Angles

Triangles and angles represent masculinity, movement, and dynamism. They can create a sense of action, excitement, and tension in a room. That’s why they’re popular in entertainment areas and exercise rooms.


The psychology of interior design is a complex topic, and it requires a deep understanding of how colors and shapes interact with our emotions, thoughts, and behaviors. When it comes to designing a space, it’s crucial to consider how these factors can impact the overall atmosphere and mood of the room. By carefully selecting colors and shapes that reflect the desired emotional response, a designer can create a space that not only looks good but also feels good.
