A color is described as a Y′ component and two chroma components U and V. The prime symbol (') denotes that the luma is calculated from gamma-corrected RGB input and that it is different from true luminance. [1] Today, the term YUV is commonly used in the computer industry to describe colorspaces that are encoded using YCbCr. [2]
Pixel formats used in Y'CbCr can be referred to as YUV too, for example yuv420p, yuvj420p and many others. In a similar vein, the term luminance and the symbol Y are often used erroneously to refer to luma, which is denoted with the symbol Y'. The luma (Y') of video engineering deviates from the luminance (Y) of color science (as defined by CIE).
YCbCr is sometimes abbreviated to YCC.Typically the terms Y′CbCr, YCbCr, YPbPr and YUV are used interchangeably, leading to some confusion. The main difference is that YPbPr is used with analog images and YCbCr with digital images, leading to different scaling values for U max and V max (in YCbCr both are ) when converting to/from YUV.
ChromaFlair paints contain no conventional absorbing pigments; rather, the pigment is a light interference pigment. The color observed is created entirely by the refractive properties of the flakes, analogous to the perception of rainbow colors in oil slicks.
Cabinet Paint Color: Tea Light by Benjamin Moore. Ngoc Minh Ngo. Barn Red Kitchen. In this Mississippi hunting lodge, unique bark cabinet panels are surrounded with a dark gray-green.
The part of a molecule responsible for its color is called the chromophore. [4] [5] Light encountering a painted surface can either alter or break the chemical bonds of the pigment, causing the colors to bleach or change in a process known as photodegradation. [6] Materials that resist this effect are said to be lightfast.
