Light and color psychology: The difference between warm and cold light

Light plays a crucial role in the design of rooms and influences not only the atmosphere, but also our emotions and perception. An important aspect is the temperature of the light, which is measured in Kelvin (K). This can be divided into two main categories: warm light and cold light. In this article we explain the differences and how they affect our environment.

Warm light (reds and yellows):

Warm light has a lower Kelvin temperature, in the range of 2000K to 3000K. It is often perceived as cozy, inviting and relaxing, similar to the light of a sunset or a candle. Ideal for living spaces such as bedrooms and living rooms, it creates a cozy and stress-free atmosphere.

Cold light (blues and whites):

Cold light has a higher Kelvin temperature, usually between 4000K and 6500K. It has an activating, refreshing effect and promotes concentration. It is used in work environments such as offices or clinics to increase alertness. In living spaces it can be perceived as cold and impersonal.

The difference between warm and cool light extends beyond color temperature and influences the emotional impact indoors. The choice between the two depends on the intended use of the space and the desired emotions. This understanding can help you create the perfect lighting for your needs and control the atmosphere in your home or workplace.
