Lab Color space, sometimes called CIELAB, is a color model similar to the CMYK, RGB, sRGB, or Adobe RGBcolor spaces. Yet, it’s primarily designed to represent color in a way almost the same as the human color perception and human vision. ...
A guided tour of the CIELAB reference color space, pictures of color spaces (camera input profile, ProPhotoRGB, monitor profile, sRGB, AdobeRGB, printer profile, shown inside CIELAB, plus definitions of eight basic color management concepts.
Color Spaces of TVs and Computer Monitors Maybe Are Not What You ThinkUsing a spectrometer, I have measured the output of TVs and computer monitors. Some examples are shown in Figure 5 - 9. Note that the response functions are not simple Gaussians, but have significant response at ...
In this chapter, we will look at three of these terms – color models, color spaces, and color profiles – and examine why it is important to develop a decent understanding of these concepts when working with color in code.Color models To understand the nature of something, it can be ...
Since the adoption of the color spaces CIELAB and CIELUV by the CIE in 1976, several other uniform spaces have been developed. We studied most of these spaces and evaluated their uniformity for small as well as larger color differences. Therefore, several criteria have been defined based on co...

Lab is a standard and standardized color space, used for instance as one of two Profile Connection Spaces in color management operations (the other is CIE XYZ). If it wasn't consistent, the whole thing would fall apart. Lab is supposed to be a reference. Rounding errors can happen, partic...
