The Temperature class provides methods for setting the color temperature (in Kelvin) of an image when you are using a color camera. The class will use the sensor's hardware gain controls for the setting, as far as possible. In addition, you can choose between different color spaces. A specific color temperature will result in slightly differing RGB values, depending on the selected color space.
The color temperature is the temperature to which a black body radiator has to be heated to glow and give off light in the corresponding color. Warm light (reddish) has a lower color temperature than cold light (bluish). The following table lists a few example values:
