Defining and Communicating Color: The CIELAB System
cdn-s3.sappi.comquantifying and communicating color. CIELAB is the reference color model used by the paper making and graphic arts industries. CIELAB forms the foundation of color management and is generally the ICC profile connection space used for gamut mapping. The basic architecture and operating premise of CIELAB is
Gernot Hoffmann Color Printer Test Pages
www.docs-hoffmann.deGray accuracy: page 9 shows a CIELab grayscale chart, coded by sRGB. This will be printed mostly by K-only because of an internal interpretation of R=G=B. Page 10 shows a similar CIELab grayscale chart. B is a little modified. This page should be be printed always by CMYK rich black, nearly as neutral gray.

While the maximum possible distance between two colors in the CIELAB space (assuming sRGB input images) is limited, the spatial distance
CIE L*a*b* Color Scale
cobra.rdsor.roThe CIELAB color scale is an approximately uniform color scale. In a uniform color scale, the differences between points plotted in the color space correspond to visual differences between the colors plotted. The CIELAB color space is organized in a cube form. The L* axis runs from top to bottom.

Continuous Color Transfer - arXiv
arxiv.orgof GMM in Lab color space(i.e., CIELAB color space), and then adopt the EM algorithm [5] to optimize the involved parameters. In other words, we regard color transfer as a parameter estimation problem. We further introduce a gradient regularization term into the objective function at the M-step, for better preservation of gradient information. A.
