4. Color temperature - Wikipedia

   en.wikipedia.org/wiki/Color_temperature

   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.

   The color temperature of incandescent bulbs – essentially the actual temperature of the hot filament – decreases as the voltage applied is reduced by a dimmer, and the light becomes visibly "warmer"; this does not happen with other technologies. However, Philips has designed LED bulbs that mimic this phenomenon when dimmed. [169]

   A final class of white LED with mixed light is dim-to-warm. These are ordinary 2700K white LED bulbs with a small red LED that turns on when the bulb is dimmed. Doing so makes the color warmer, emulating an incandescent light bulb. [39]
