Color temperature is a measurement of the hue of a light source, and it is measured in degrees Kelvin (K). It refers to the color of the light that is emitted from a source, and it is based on the temperature that a perfect black body radiator would have to reach in order to produce light of that color. For example, a candle flame has a color temperature of around 1850K, while a blue sky on a sunny day has a color temperature of around 10,000K.

Color temperature is an important concept because it can have a significant impact on the final appearance of an image or video. The color temperature of the light source can affect the mood and tone of the image, and it can also impact the accuracy of the colors in the scene. For example, if a photographer takes a photo of a white object under a warm, yellowish light source, the object may appear yellowish in the photo. By understanding color temperature and how it impacts the final appearance of an image, photographers and videographers can adjust the color temperature of the lighting in order to achieve the desired look and feel.

The scale for color temperature ranges from around 1,000K to over 10,000K. Lower color temperatures (around 1,000K to 3,000K) are considered warm and appear more yellow or orange in color. These temperatures are often associated with sunrise, sunset, or incandescent lighting. Mid-range color temperatures (around 3,000K to 5,000K) are considered neutral and are similar to natural daylight. Higher color temperatures (around 5,000K to 10,000K) are considered cool and appear more blue in color. These temperatures are often associated with cloudy skies or fluorescent lighting.

Color temperature can be adjusted using various tools and techniques, including white balance settings on a camera or post-processing software. White balance refers to the adjustment of the color temperature to ensure that white objects appear white in the final image. In some cases, photographers and videographers may intentionally use lighting with a specific color temperature to achieve a desired look or mood in the image or video.

In summary, color temperature is a measurement of the hue of a light source and is measured in degrees Kelvin. It can have a significant impact on the mood, tone, and color accuracy of an image or video, and understanding how to adjust it is an important skill for photographers and videographers. Adjusting color temperature can be done using various tools and techniques and can be used to achieve a desired look or mood in the final image or video.
