What is XYZ color code?
The XYZ color space, established by the CIE (International Commission on Illumination) in 1931, is the foundational model for all modern color management systems. It mathematically defines the relationship between the physical wavelengths of light and human color vision. In this model, 'Y' corresponds to luminance (brightness), while 'X' and 'Z' serve as virtual components to describe chromaticity. Because it encompasses all colors visible to the human eye, XYZ serves as the standard reference space for converting colors between different devices and color spaces.
What is LAB color code?
The LAB color space (specifically CIELAB or CIE L*a*b*) is a color standard defined by the International Commission on Illumination (CIE) in 1976. It represents colors with three dimensions: 'L' for lightness (ranging from 0 for black to 100 for white), 'a' for the green-red color component, and 'b' for the blue-yellow color component. Unlike RGB or CMYK, LAB is designed to be device-independent, meaning it defines colors based on human perception rather than how they are produced by a specific screen or printer. This makes it an crucial intermediate space for converting between different color profiles.
