K indicates the color temperature in kelvins, and M indicates the color temperature in micro reciprocal degrees. The color temperature of the electromagnetic radiation emitted from an ideal black body is defined as its surface temperature in kelvins, or alternatively in micro reciprocal degrees (mired). [11]
Before the advent of powerful personal computers, it was common to estimate the correlated color temperature by way of interpolation from look-up tables and charts. [18] The most famous such method is Robertson's, [ 19 ] who took advantage of the relatively even spacing of the mired scale (see above) to calculate the CCT T c using linear ...
Planckian locus in the CIE 1931 chromaticity diagram. 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.
Color rendering index shown as color accuracy. A color rendering index (CRI) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with a natural or standard light source.
The color analysis filter is a great way to find your colors if you're on a budget — but know that it won't go into nearly as much detail as a professional like Dobkine would. What you should ...
Color chips or color samples from a plastic pellet manufacturer that enables customers to evaluate the color range as molded objects to see final effects. A color chart or color reference card is a flat, physical object that has many different color samples present. They can be available as a single-page chart, or in the form of swatchbooks or ...

In photography, mireds are used to indicate the color temperature shift provided by a filter or gel for a given film and light source. For instance, to use daylight film (5700 K) to take a photograph under a tungsten light source (3200 K) without introducing a color cast , one would need a corrective filter or gel providing a mired shift
