As you learn more about interior design, we quickly realize that lighting plays a crucial role. It is important in creating the desired atmosphere as well as the perception of a space. One essential aspect of lighting that often goes unnoticed by many is color temperature. By understanding color temperature and its impact on interior design, your space will be ready for you.

What is Color Temperature?

Color temperature refers to the appearance of light produced by a light source, measured in degrees Kelvin (K). It determines whether the light emitted appears warm, cool, or neutral. The lower the temperature, the warmer the light, while higher temperatures produce cooler light.

Warm vs. Cool Light

Warm light, typically found in incandescent bulbs, ranges from 2,500K to 3,000K. It exudes an intimate feeling and works well in spaces where relaxation and comfort are the primary goals, like living rooms and bedrooms. Warm light creates a welcoming atmosphere and complements earthy tones and warm color palettes.
Cool light, found in fluorescent and LED bulbs, has a higher color temperature, usually between 4,000K and 6,500K. It offers a crisp, bright, and refreshing feel to a room. Cool light is ideal for spaces that require focus and productivity, such as kitchens, offices, and bathrooms. It pairs well with sleek, contemporary designs and cooler color schemes.

Color Temperature + Materials

Lighting has a profound impact on how colors and materials are perceived within a space. The color temperature can alter the appearance of surfaces, paints, and textures, dramatically influencing the overall mood.
Warm light tends to enhance warmer tones, making reds, oranges, and yellows appear more vibrant and rich. It can also soften cooler colors, making blues and greens appear less dominant.

Conversely, cool light can intensify cooler hues, making blues, greens, and purples appear more pronounced. It may also mute warmer colors, making reds and oranges appear duller.


Additionally, color temperature affects the perception of materials. Warm light enhances warm-toned materials like wood, brick, and natural fibers, giving them a cozy, organic feel. On the other hand, cool light can highlight cool-toned materials like glass, metal, and concrete, enhancing their sleek and contemporary characteristics.

Pick the Right Color Temperature for Your Space

When selecting the appropriate color temperature for your space, consider the function and desired ambiance.
In social areas like living rooms or bedrooms, opt for warmer light to create a soothing and inviting environment. Warm light promotes relaxation, making it ideal for unwinding after a long day or hosting intimate gatherings.
For task-oriented areas such as kitchens, offices, or bathrooms, cooler light offers better visibility and concentration. It provides a bright and stimulating atmosphere, allowing you to focus on various activities like cooking, working, or grooming.
In open-plan spaces, you can combine warm and cool lighting sources strategically to create various zones or highlight specific features. This approach adds depth and dimension to the space while offering flexibility in setting different moods at different times.

More to Consider

While color temperature plays a significant role in lighting design, remember to consider natural light as well. The time of day and the presence of natural light can influence the perceived color temperature within a space.
Moreover, the type and design of light fixtures will also affect the distribution and quality of light. Read our other post about lighting types here. Choose fixtures that complement your interior style and ensure that they emit the desired color temperature consistently.
