## Planckian Locus Wikipedia

### Planckian locus - Wikipedia.

In physics and color science, the Planckian locus or black body locus is the path or locus that the color of an incandescent black body would take in a particular chromaticity space as the blackbody temperature changes. It goes from deep red at low temperatures through orange, yellowish white, white, and finally bluish white at very high temperatures.. A color space is a ....

### Color temperature - Wikipedia.

The NTSC and PAL TV norms call for a compliant TV screen to display an electrically black and white signal (minimal color saturation) at a color temperature of 6500 K. On many consumer-grade televisions, there is a very noticeable deviation from this requirement. However, higher-end consumer-grade televisions can have their color temperatures adjusted to 6500 K by using a ....

### CIE 1931 color space - Wikipedia.

In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see ? Definition of the CIE XYZ color space).Setting Y as luminance has the useful result that for any given Y value, the XZ plane will contain all possible chromaticities at that luminance.. The unit of the tristimulus values X, Y, ....

### Planck's law - Wikipedia.

The spectral radiance of Planckian radiation from a black body has the same value for every direction and angle of polarization, and so the black body is said to be a Lambertian radiator. Different forms. Planck's law can be encountered in several forms depending on the conventions and preferences of different scientific fields..

### Standard illuminant - Wikipedia.

In several of these studies, the daylight locus is notably closer to the Planckian locus than in Judd et al. Daylight locus in the CIE 1960 UCS. The isotherms are perpendicular to the Planckian locus. The two sections of the daylight locus, from 4000-7000 K ....

### Boltzmann constant - Wikipedia.

Macroscopically, the ideal gas law states that, for an ideal gas, the product of pressure p and volume V is proportional to the product of amount of substance n (in moles) and absolute temperature T: =, where R is the molar gas constant (8.314 462 618 153 24 J?K -1 ?mol -1). Introducing the Boltzmann constant as the gas constant per molecule k = R/N A transforms the ....

### Color - Wikipedia.

The Planckian locus is shown with color temperatures labeled in Kelvins. The outer curved boundary is the spectral (or monochromatic) locus, with wavelengths shown in nanometers. Note that the colors in this file are being specified using Adobe RGB. Areas outside the triangle cannot be accurately rendered since they are outside the gamut of ....

### sRGB - Wikipedia.

sRGB is a standard RGB (red, green, blue) color space that HP and Microsoft created cooperatively in 1996 to use on monitors, printers, and the World Wide Web. It was subsequently standardized by the International Electrotechnical Commission (IEC) as IEC 61966-2-1:1999. sRGB is the current defined standard colorspace for the web, and it is usually the assumed ....

### CIE 1960 color space - Wikipedia.

Background. Judd determined that a more uniform color space could be found by a simple projective transformation of the CIEXYZ tristimulus values: (? ? ? ? ? ?) = ()(Note: What we have called "G" and "B" here are not the G and B of the CIE 1931 color space and in fact are "colors" that do not exist at all.). Judd was the first to employ this type of transformation, and many others ....

### Color rendering index - Wikipedia.

Using the 2? standard observer, find the chromaticity co-ordinates of the test source in the CIE 1960 color space.; Determine the correlated color temperature (CCT) of the test source by finding the closest point to the Planckian locus on the (u, v) chromaticity diagram.; If the test source has a CCT < 5000 K, use a black body for reference, otherwise use CIE standard illuminant D..

### Black body - Wikipedia.

A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.The name "black body" is given because it absorbs all colors of light. A black body also emits black-body radiation.In contrast, a white body is one with a "rough surface that reflects all incident rays completely and uniformly in all ....

### Color correction - Wikipedia.

Color Correction is a technical process that fixes color issues and makes footage appear as naturalistic as possible. The idea is for colors to look clean and real, as human eyes would see them in the real world. Basically, correcting problems of the underlying image by balancing out the colors, making the whites appear white, the blacks appear black, and making sure that ....

Figure 44: The Planckian locus visualized on a CIE 1931 chromaticity diagram (source: Wikipedia) The easiest way to compute RGB values from this locus is to use the formula described in . Krystek's algorithm (equation $$\ref{krystek}$$) works in the CIE 1960 (UCS) space, using the following formula where $$T$$ is the desired temperature, and ....

### Yellow - Wikipedia.

Yellow is the color between green and orange on the spectrum of light.It is evoked by light with a dominant wavelength of roughly 575-585 nm.It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal ....

### Color Differences of LED Lighting - 2.7K, 3K, 4.3K, 5K, 6K.

Take a look at the Planckian locus graph below. The main area to pay attention to is the black curved line inside of the colored area. As you can see from the graph, 3000, 4000, and 6000 numbers are all shown. This range contains the most commonly available colors of LED lighting for headlights, parking lights, and fog lights. 2700K = AVG..
