värilämpötilojen

Värilämpötila, also known as color temperature, is a measure of the color appearance of light, specifically the relative warmth or coolness of a light source. It is measured in Kelvin (K), a unit of temperature. The color temperature of a light source is determined by the peak wavelength of its emitted light.

Light sources with a color temperature below 2700K are considered warm or red, while those above 5000K are cool or blue. The human eye perceives light with a color temperature around 6500K as neutral or white. This is why many indoor lighting systems are designed to have a color temperature around 6500K to mimic natural daylight.

Color temperature is an important factor in lighting design, as it can significantly impact the mood and atmosphere of a space. For example, warm light (below 2700K) can create a cozy and inviting atmosphere, while cool light (above 5000K) can make a space feel more energetic and alert.

In photography, color temperature is used to adjust the white balance of an image, ensuring that the colors appear natural and accurate. In astronomy, color temperature is used to classify stars based on their surface temperature.

In summary, color temperature is a measure of the color appearance of light, measured in Kelvin. It is an important factor in lighting design, photography, and astronomy.
