Do you know what color temperature is it? How to choose the color temperature? 

 

Because most of the light emitted are collectively referred to as white, so color temperature or correlated color temperature table source that is used to refer to the extent of its light hue dialogue, in order to quantify the performance of light and color of the light source. According to the theory of Max Planck, the one with the ability to completely absorb the radiation standard blackbody heating, the temperature gradually increased luminosity has changed; blackbody curve (Black body locus) CIE color coordinates displayed on the blackbody from red - orange - - yellow - yellow and white - white - blue and white process. Blackbody warmed to appear with the same or close to the light source when the light color temperature, defined as the correlated color temperature of the light source, called the color temperature to absolute temperature K (Kelvin or called Kelvin) units (K = ℃ + 273.15). Thus, in bold red when heated to a temperature of about 527 ℃ namely 800K, other light color temperature change.

 

More bluish light color, color temperature higher; reddish color temperature is the lower. Among the day light color painted light tandem time: 40 minutes after sunrise yellow light color, color temperature 3,000K; white midday sun, rose to 4,800-5,800K; cloudy noon is about 6,500K; before sunset light color reddish, color temperature was further reduced to paper 2,200K. Other correlated color temperature of the light source, due to the correlated color temperature blackbody radiation actually is closer to the light source color of the light source color performance evaluation value is not an accurate color contrast, so the two have the same color temperature of the light source, There may still be a little difference in the appearance of light and color. color alone can not understand the source of the object's color capabilities, or how to reproduce the color of an object under the light source.

 

Correlated color temperature of the light source in different environments:

Northern skies 8000-8500k

Cloudy 6500-7500k

The midday summer sun 5500k

Metal halide lamps 4000-4600k

Afternoon sunlight 4000k

Cool camp light 4000-5000k

High pressure mercury lamp 3450-3750k

Camp 2500-3000k warm light

Halogen 3000k

Tungsten 2700k

HPS 1950-2250k

Candle light 2000k

 

Different color temperature of the light source, the light colors are different.

Color temperature below 3300K have stable atmosphere, warm feeling;

color temperature 3000--5000K intermediate color temperature, there is a refreshing feeling; feeling cold color temperature of 5000K or more. Different color different light sources make the best environment.

 

Color temperature is the human eye to light emitter or white reflectors, which is physics. A feeling integrated complex factors Neo body and psychology, also vary. Color on the TV (phosphor) or photography (reflectors) is a way to change employers, for example, in photography we use hot 3200K white light (3200K), but we add a red filter over the lens filtered through a little red light to make the photo look a little lower color temperature; the same token, we can also reduce a little red (but minus the number of too much will affect the performance of normal red) on the TV so that the screen looks a bit high color temperature.

 

On the color temperature preferences because people may be, with this scene we see daily views about, for example, people close to the equator, the average color temperature is seen daily in 11000K (8000K (evening) ~ 17000K (noon)), it is more like a high color temperature (looks real), on the contrary, at higher latitudes (average color temperature of about 6000K) who would prefer a low color temperature (5600K or 6500K), which means that if you are using a high TV color temperature to the performance of the Arctic landscape seems to feel partial green; the contrary, if you are to see low color temperature subtropical style TV, you'll feel a little reddish.

TV or color temperature of the display is how to define it? Because the scenery in China throughout the year the average color temperature between about 8000K ~ 9500K, so in the production of television programs are in the audience for the color temperature of 9300K to photography. But Europe because usually we have differences in color temperature and at an average of about 6000K color temperature throughout the year as a reference made, so when we look at those foreign films, you will find the most suitable watch 5600K ~ 6500K. Of course, this difference will therefore make us feel a fierce sense of reddish color temperature, warm see the computer or TV screen when Europe and America, some do not adapt.

 

Is the color temperature of 9300K black eyes who look white but blue-eyed people saw blue eyes 6500K is bluish white people saw that we Chinese people looked yellowish.
