ambient color temperature
The color temperature was a unit of measurement that represented the color composition of light. The unit was "K"(Kelvin). It was a physical quantity used to define the color of a light source in illumination. In theory, the blackbody temperature referred to the color of an absolute blackbody after it was heated from absolute zero (-273 ° C). After the blackbody was heated, the color gradually changed from black to red, yellow, white, and finally blue light. When heated to a certain temperature, the spectral composition of the light emitted by the blackbody was called the color temperature at this temperature. If the light emitted by a light source has the same spectral composition as the light emitted by a black body at a certain temperature, it is called a certain K color temperature. However, it was difficult to determine the specific value without more background information because different environments had different color temperatures. For example, the color temperature of indoor lighting may be between 2700 - 4000K (warm light to neutral light range), and different lamps, natural light sources (such as sunny and cloudy), etc. will affect the color temperature of the environment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Color temperature for design
In lighting design, the choice of color temperature depends on the specific needs of the place. The following are the color temperature design suggestions for different locations: - ** Home environment **: - The overall color temperature of the home decoration was recommended to be 3500K-4000K. Among them, the 3500K color temperature was warm, giving people a warm, lazy, and relaxed feeling, while the warm white light around 4000K made people happy and comfortable. However, when the use of different spaces in the home is changeable, such as the living room and bedroom, it is best to choose an LED lamp with a color temperature that can be adjusted. For example, the bedroom is suitable for 3000 - 3500K color temperature lighting before going to bed, which is good for sleep, and high color temperature lighting is good for thinking things; if the bedroom uses a color temperature lamp above 5000K, excessive blue light will suppress the brain's meltdown release, affecting sleep and sleep quality. According to the National Building Lighting Design Standard, the color temperature of guest rooms and bedrooms should be less than 3300K; the kitchen is not recommended to use warm light. A color temperature of 3500 - 4000K with a color rendering index of more than 90 is better, which can make the taste sensitive and the space clean and tidy. Two color temperatures can be prepared for the bathroom, and the comfortable color temperature should be selected according to the season. - ** Office **: Generally choose 4000 - 5000K, close to natural light, making people feel bright and focused, so that they can quickly enter the working state to improve efficiency. - ** Shops, hospitals and other places **: suitable for cold light (above 5000K), can enhance the brightness of the space. - ** Lobby, restaurant, bathroom, etc. ** Neutral light (3300K-5000K) can create a natural feeling in the space. - ** Living room, bedroom, exhibition area, etc. **: Warm light (below 3300K) can be used to decorate the atmosphere. At the same time, when choosing the color temperature, psychological and aesthetic issues should also be considered. It depends more on factors such as illumination, the color of the interior surfaces and furniture, the climate environment, and the application site conditions. Usually, warm color temperature should be used in low-illumination places, intermediate color temperature should be used in medium-illumination places, and cold color temperature should be used in high-illumination places. In warm climate conditions, cold color temperature may be more inclined, and in cold conditions, warm color temperature may be more inclined. Under normal circumstances, intermediate color temperature should be used. It was also best to use lamps of the same brand and batch in the same space to reduce the influence of color temperature difference and color tolerance. If there was no brilliant design technique, try not to use two color temperatures in the same space. If used, the difference should not exceed 500K. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The color temperature of the makeup lamp
The color temperature of the makeup lamp was generally 5000K-6500K. This color temperature range could provide sufficient brightness and accurate color reproduction, which would help make makeup more precise and accurate. At the same time, the light under this color temperature would not be too dazzling or dim, which could protect the eyes and provide a better observation effect. If you want a more professional makeup effect, you can add a soft light source around the mirror, such as LED light strips or soft light boards, to make the lighting more uniform and soft. You can also adjust the brightness and angle of the light to suit different scenes and makeup needs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Dual-color photography
Dual-color photography was a photography method that used dual-color temperature (hue) effects. It was difficult to encounter dual-color temperature environments in natural environments. Usually, dual-color temperature images could only be shot at night when the artificial environment light source was complex or indoors, and the distance between different color temperature light sources was close. When shooting outdoors or indoors, there was a chance to shoot dual-color temperature images when the environmental light sources of different color temperatures were close to each other. You can use a flash plus a filter or use some continuous lights that can change the color temperature to create a dual color temperature effect. When shooting with a continuous light source, if the continuous light source is too bright, the model's eyes will not be able to open. At this time, the brightness should be adjusted to the intensity of the eyes, and then slightly increase the sensitivity, increase the aperture, and slow down the shutter speed to obtain a brighter exposure value. However, in this way, under the large aperture and slow shutter speed, pay attention to accurate focus and avoid shaking the hand; When the environmental light source is weak and the model is far away from the light source, it is also necessary to increase the sensitivity, increase the aperture, and slow down the shutter speed to obtain a higher exposure value. If you use a high-wattage flash for shooting, you can overcome the things that need to be paid attention to when shooting with a continuous light. Some mobile phones, such as the Oppo Find X, added a two-color light effect in portrait mode, allowing them to take photos with unique styles. In addition, there were photography lights with dual color temperature (3200k-5600k) design like the Tukuang PT -24B dual-color shadowless LED photography light. It used a patch lamp bead to switch between cold and warm colors without significantly reducing the brightness. Through the function adjustment button, it was easy to play with the dual-color temperature without changing the camera settings, greatly increasing the playability of photography. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Color temperature preference in America and Europe
European people's eyes were blue and more sensitive to light. They preferred low color temperature screens. For example, in terms of lighting, European light culture preferred low color temperature and high display. Low color temperature light made white skin not pale, and warm colors could create different ambiances and control the saturation of the picture. In North America and Europe, blue represented trust, security, and authority. It was considered a color that comforted and calmed people. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What are the benefits of TV color temperature selection?
Choosing a different TV color temperature has the following benefits: - Choose a color temperature of around 4000K, 4500K, and 5000K. The screen is yellow and gentle, and it will not irritate the eyes. It is suitable for daily viewing and is more friendly to the eyes. - The lower color temperature values (such as 4000K, 4500K) leaned towards warm yellow light, which was suitable for expressing some close-up and cultural landscapes. - Higher color temperatures tend to be cold, and cool colors can make the sky and other natural scenery clearer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the best color temperature for car headlights?
The choice of the best color temperature for car headlights depends on many factors. If it was often rainy and foggy weather, the light with a lower color temperature would have better penetration. For example, the color temperature of a halo lamp was generally around 3500K. This kind of yellowish light could allow the driver to see the road better in rainy and foggy weather. For Xenon lamps and LED headlights, the relatively compromised 4300K color temperature was more suitable for various car situations. Not only was it practical, but it also had a better visual effect after being lit. If the weather was good and there was no rain, snow, or smog, a 4800K or 5500K was also a good choice. The more mainstream LED headlights had a color temperature of 4300K, 5000K, 5500K, 6000K, 6500K, and others such as 3000K and 5800K. However, it should be noted that the larger the value, the higher the brightness of the light. The brightness of the light has nothing to do with the color temperature. The color temperature only represents the color of the light. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to adjust the color temperature of the LCD TV
Generally speaking, LCD televisions could adjust the color temperature according to personal preferences. Usually, you could enter the TV's settings menu and find options related to image settings or display settings, including color temperature adjustment. Cool colors could make the picture look clearer, suitable for movies, dramas, and other content, while warm colors were more suitable for daily viewing, and the colors were softer. In addition, some LCD televisions may have special color temperature preset modes, such as "standard","cool","warm", etc., users can directly select these modes to quickly adjust the color temperature. There were also some LCD televisions that had a color temperature correction function. For example, Changhong's new color temperature correction method was to input a test signal to the LCD TV, determine the R value, G value, and B value of the test signal, determine the unit change of the color coordinate and the unit change of the brightness, and then obtain the upper and lower threshold values of the brightness and the target color coordinate. It also obtained the current color coordinate and current brightness of the LCD TV that needed to be corrected. According to the size relationship between the current brightness and the brightness upper and lower threshold values, the unit variation, the target color coordinate, and the current color coordinate, the color coordinate corresponding to the R & G correction value is determined, and whether the color coordinate is within the error range of the target color coordinate is judged respectively. If so, the R & G correction value is written into the liquid crystal television, thereby realizing the color temperature correction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is there any software to adjust the color temperature of the phone?
Yes, for example, the "Screen Color Temperatures" mobile phone application could automatically adjust the color temperature of the screen according to the sunrise and sunset time to simulate natural lighting. It also provided a variety of color temperature options. The user could freely adjust the color temperature by sliding the slide bar, changing the screen from a cool color (more blue light) to a warm color (less blue light), or fine-tuning it according to personal preferences. The Twilight app was also a good eye-protection software for mobile phones. It supported color temperature and other parameters to adjust the device screen to adapt to the time of the day. After sunset, it would filter out the blue spectrum on the screen of the phone or tablet and replace it with a softer red light. The filter strength would also be adjusted smoothly according to the specific situation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
