What Is LED Color Temperature?
Color temperature (CT) is a temperature measurement method, this concept is based on an imaginary black object, when heated to different temperatures, it shows different colors and emits different light colors.
After the black object is heated, it gradually turns from black to red, turns yellow, turns white, and finally emits blue light. It is measured in degrees of Kelvin (K) on a color temperature scale from 1,000 to 10,000.
Due to the different color temperatures, the white color is diverse. The warm white light is 2800K-3200K, neutral white is 4000K-5000K, daylight white is 6000K-6500K, and the cool white light is 7000K-9000K.
Here is a general rule so that you can better understand the Kelvin color temperature. The lower the color temperature, the warmer the color. The higher the color temperature, the cooler the led light color, and relatively speaking, the brightness will be brighter.
The color temperature calibrated by this method is exactly the opposite of what the general public thinks of as "warm" and "cold". For example, people usually feel that red, orange and yellow are warmer, white and blue are cooler, but the color temperature of red is actually the lowest and then gradually increases are orange, yellow, white, and blue, with blue being the highest color temperature.
When shooting with natural light, because the color temperature of the light is not the same in different time periods, the color of the photos taken is also not the same. For example, when shooting under a clear blue sky, the light color temperature is relatively high, so the photos tend to be cooler. And if you shoot at dusk, the color temperature light is lower, so the photo is warmer.
