Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields Color temperature is a simplified way to characterize the spectral properties of a light source. While in reality the color of light is determined by how much each point on the spectral curve contributes to its output, the result can still be summarized on a linear scale. White Balance Occasionally the question arises as to how to reproduce the "real" color of light sources in a rendered environment. I set out to research this subject, and found a lot of very contradictory information. Some approaches try to categorize light sources by their color temperature. Some then try to come up with some meaningful way of converting that color temperature to RGB values to use in programs like Lightwave or Cinema 4D. Ultimately these approaches all fail to take into account several realities that work against trying to come up with a unified approach to light coloring and rendering. The human visual system is very good at "white balancing" what we look at. As long as the scene we are viewing contains a continuous spectrum of colors, we interpret the light as "white". In reality, the incandescent light we light our homes with is quite orange. Daylight is very blue. Fluorescent lights vary from sickly greens to reddish purples. And yet, we see all these lighting situations as more or less neutrally colored. In the real world, light consists of all visible colors, not just red, green, and blue wavelengths. The RGB color system that we use in computer graphics arose out of a peculiarity of human perception - we have structures in our eyes called "cones" that respond to red, green, and blue light sources. A monochromatic yellow light excites both the red and green cones in our eyes, and we see it as yellow. Such a yellow light in the real world would not allow a red object to appear red, or a green object to appear green. But in computer graphics a yellow light has both a red and green component, and so allows objects with those colors to appear fully colored. This is a limitation of many computer graphic programs at the moment. Film cameras cannot compensate for the varying shades of light in the way that our visual sense can. Thus, we have daylight film which has heavy orange filtering to tone down the blue quality of outdoor light. We have indoor film which has a boosted blue response to even out the amber lighting. For fluorescent situations, we can use a combination of film type and filters to color balance the scene we are photographing. If we were to pick a particular color of light, say daylight, and say that it is "white" and photograph everything, indoors and out, with a film stock that renders daylight as white, all of our indoor shots would be shades of orange and amber, and outdoor shots under blue sky would be intensely blue. This would be undesirable. Thus too it is undesirable to pick a similar approach with our 3D rendering of light. We have to be relative - and choose a light color to be "white" in our scene, with other types of light sources being colored relative to that one. In this way we can produce our synthetic "photos" to produce a pleasing result in our final renders. Of course, to understand how different types of light sources relate to each other, it is important to understand how these light sources work. To do this we are going to look at 3 basic types of light source. The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable hue to that of the light source. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing.. Compact fluorescent light bulbs use up to 75% less energy and last up to 10 times longer than standard light bulbs. For photo and video studio lighting. 5500K color temperature
When a black object such as a piece of iron is heated up, it changes colour depending on the temperature that it’s heated to. Turns out that this range of colors is very useful for describing the colour tint of white light. Generally, colour temperature is a quality feature of light, indicating whether the light colour is Fluorescent lamp 840. 4,000 K = balanced blue and red component = neutral, clear light.

. Daylight has a rather low color temperature near dawn, and a higher one during the day. Therefore it can be useful to install an electrical lighting system that can supply cooler light to supplement daylight when needed, and fill in with warmer light at night. This also correlates with human feelings towards the warm colors of light coming from candles or an open fireplace at night. Color Temperature refers to the color of a light source. Different types of light sources have an Natural daylight is blue in its color and will be somewhere between 5600 and 10000 K. Interior, light..
“Warm white” generally means a yellow-ish type of white, and “cool white” means a blue-ish kind of white. Somewhere in between lies “daylight white”, which is pretty much the whitest kind of white. Cool, warm and daylight are pretty imprecise terms, though. It’s useful to have a more accurate system to indicates the tint of the light. That system is called the colour temperature, or Correlated Colour Temperature (CCT).The selection of light colour is ultimately personal choice but there are some factors which should be considered. A warm white light colour is far softer on the eye and creates a warm ambiance and accordingly is normally the choice for interior domestic spaces. Additionally the warm white colour will not show up every detail on a surface and is more flattering when peoples' faces are seen as and fine wrinkles or blemishes will not be so prominent and visual skin toning will look better. In contrast the cool white light is much better for visual clarity and therefore is the normal choice for office environments and work environments where vision is of paramount importance. At the top end of the scale there is daylight colour which is the best for vision and accordingly is normally chosen by people who are reading and artists because it shows colours as they would be seen outdoors. The fact that daylight white gives improved vision means that it is the natural choice for the partially sighted and care homes.

Why do we use the term “temperature” to describe the colour? Light doesn’t have a “temperature”, so why do we use this term, and what does it have to do with colour?

Interestingly, as the intensity of light increases, the perception of the color temperature changes. For example, on a very bright day, the color temperature of the light may be as high as 8,000 or 10,000K, but we do not perceive that we are bathing in blue light, although the light from the blue sky is the predominant source.So, you may ask… is the sky blue because the atmosphere is heated to 10,000 degrees Kelvin? No, the sky is blue because of the light scattering in the atmosphere; the shorter blue wavelengths are absorbed and re-radiated by gas molecules, resulting in a blue looking sky.

I learned that it is not only the brightness that makes our eyesight better but more on the color of it. Cool white and natural daylight color have the tendency of spreading the light widely, affecting the eye lens, especially when you have cataract at old age. The reddish or yellowish color of warm white light does not scatter the light widely in the eye lens, thus, it is recommended for reading. The red color also improves digestion, taste, internal organs, and even our memory. Notice that most Chinese restaurants use red paintings in their surroundings.
