The color temperature scale describes only the color of light emitted by a light source, which may actually be at a different (and often much lower) temperature. [1] [2] Color temperature has applications in lighting, [3] photography, [4] videography, [5] publishing, [6] manufacturing, [7] astrophysics, [8] and other fields.
[3] [4] [5] In practice, light sources that approximate Planckian radiators, such as certain fluorescent or high-intensity discharge lamps, are assessed based on their CCT, which is the temperature of a Planckian radiator whose color most closely resembles that of the light source. For light sources that do not follow the Planckian distribution ...

[23] [59] This usually takes the form of one green light on the dashboard on cars from the 1950s or older, or two green indicator lights on cars from the 1960s to the present, and a rhythmic ticking sound generated electromechanically or electronically by the flasher. It is also required that the vehicle operator be alerted by much faster- or ...
Rods impact the eyes' light sensitivity and are responsible for peripheral vision, according to the American Academy of Ophthalmology. Cats can see up to six times better than the average human in ...
A standard illuminant is a theoretical source of visible light with a spectral power distribution that is published. Standard illuminants provide a basis for comparing images or colors recorded under different lighting.
A family’s Christmas portrait is going viral — for the wrong reasons. In a TikTok video, mother and nursing student Taylor, who goes by @craveslim on social media, reacted to her 5-year-old ...
A Minnesota couple has reportedly been sentenced to four years after they locked their children in cages for "their safety." The couple was arrested and charged with 16 counts in June 2023. They ...
