Color temperature is a Unit of measurement that represents the color component in the light, and refers to the color that appears after the blackbody starts to heat up. After being heated, the blackbody gradually changes from black to red, turns yellow, turns white, and finally emits a blue light. When heated to a certain temperature, the spectral composition of the light emitted by the blackbody is called the color temperature at this temperature, and the Unit of measurement is “K” (Kelvin).
If it is light that makes us see, then the color of light gives us our first impression of space.
The first step in lighting design is often to determine the basic color temperature and set a tone for the space based on the project situation.
Generally speaking, high color temperature cold light with a white to blue color gives people a refreshing and exciting feeling, while warm light with a yellow to red color gives people a warm and peaceful feeling.
So where does this impression come from?
This probably starts from the time when Pangu created heaven and earth.
The color temperature of natural light is not fixed, but constantly changes with sunrise and sunset. The color temperature in the morning is slightly red and warm, and the higher the color temperature near noon, the whiter the light color. However, at dusk, it begins to turn red and warm again.
For thousands of years, humans have worked with the sunrise, rested with the sunset, and gone back and forth, gradually forming our instinctive perception of light and color.
During the day, the color temperature is high and the brightness is high, making it suitable for active activities. In the evening, the light color warms up, and the brightness also begins to decrease. People also begin to enter a state of quiet and relaxation. Lighting a fire at night is also a continuation of this state.
So high brightness and high color temperature environments are generally suitable for work environments, such as offices, where fresh and clean light and color can easily keep people excited, or public places, such as airports and subway stations, where a bright environment is also more likely to give people a sense of security; An environment with low brightness and low color temperature is more likely to make people feel warm and calm, such as at home, hotels, and high-end restaurants, which are more suitable for this atmosphere.
