What is color temperature?
Color temperature could be defined as “the dominance of one of the colors in the light spectrum in white lights”, altering the white warm colors (Amber) or cold tones (blue) in the spectrum.
Color temperature is measured in degrees Kelvin, and applies only to white lights. If we have a source of light of any color, such as blue or green, we could not measure its color temperature. We have several types of dominant color, but the most notable are the color orange or amber and blue hues.
White lights that have dominant amber are called warm lights, because the effect we see in the lighting of a room, gives us a warm feeling.
White lights with blue color cast are lights Frias, the psychological effect that we see in a room lit with this type of lights, it gives us the feeling of finding ourselves in a cold place.
The temperature of Color has nothing to do with causing the light source or not heat. We talked about the psychological reaction produced in our brains to find an environment illuminated by this tonality. Color temperature is never 100% accurate there are factors that can cause changes in lighting.
Examples of color (kelvin) temperature
- Candle light or fire making combustion between 1,200 and 1,800 k
- Sunrise / sunset between 2,000 and 2,200 k
- Incandescent lamps: Lamps 40w to 75w between 2600 k and 2.800 k, lamps from 100w to 500w 2,800 k to 3.000 k, Dichroic and halogen lamps between 2,800 and 3,000 k
- Incandescent lamps for TV, film or photography studio between 3,200 and 3,400 k (the most used is the 3200K)
- Light of noon (summer) 5.600k
- Cloudy day between 6,000 k and 10,000 k
- Lus de el Alba between 8,000 k and 10,000 k
In reality is impossible to achieve a target without any predominance of color, which the manufacturers of lamps called white neutral (or neutral white light) actually has a small key yellow that at first glance, the human eye is unable to distinguish or appreciate.
