![]() ![]() The LAB to CMYK converter below is a useful tool that facilitates the conversion procedure for you so you can simply grab the final numbers and use them in any medium. The CIELAB color space is a device-independent color space as opposed to CMYK, which highly depends on the device’s ability to mix primary colors and also the properties of the ink itself. It is different from more common RGB and CMYK color spaces, because CieLAB is based on the CIE XYZ color space, where the L*a*b* values are calculated according to the lightness value and a set of coordinates. It is used by designers who need to produce colors that are consistent across devices. The CIELAB color space is a three-dimensional model of colors that are perceptually uniform. It is done by calculating the inverses of each component from CIELAB to CMYK. In order to convert a CIEL*a*b (or simply LAB) color space to CMYK, you need to obtain the input values and then calculate the result. Negative a* corresponds with green, positive a* corresponds with red, negative b* corresponds with blue and positive b* corresponds with yellow.This LAB to CMYK converter transforms any LAB color composition to visually acceptable CMYK color, considering applicable limitations that CMYK color gamut encounters when subjected to such conversion. L* represents lightness from black to white on a scale of zero to 100, while a* and b* represent chromaticity with no specific numeric limits. ![]() The letters L*, a* and b* represent each of the three values the CIELAB color space uses to measure objective color and calculate color differences. The CIE in CIELAB is the abbreviation for the International Commission on Illumination’s French name, Commission Internationale de l´Eclairage. As a result, organizations in many industries use CIELAB to control color and define color tolerance standards. The color space is copyright- and license-free, which means you can use it freely and integrate it into any device or system. All of these models use three data points to define and plot a color.ĬIE developed CIELAB to simplify color communication regardless of the device used. When creating the CIELAB color space, the CIE drew inspiration from the CIE 1931 XYZ color space, as well as the Munsell color system. The International Commission on Illumination (CIE) developed the L*a*b* color model in 1976 with the intent of creating a standard for color communication. In this color space, numerical differences between values roughly correspond to the amount of change humans see between colors. CIELAB or CIE L*a*b* is a device-independent, 3D color space that enables accurate measurement and comparison of all perceivable colors using three color values. ![]() To reproduce an exact desired color every time, manufacturers and designers need ways to quantify a color’s properties and determine the numerical difference between shades. ![]() This creates challenges when communicating about color. You may perceive two slightly different colors as the same or see differences in objects of identical color depending on your viewing angle and lighting. However, it won’t always distinguish colors from one another accurately. Lightness is kept separate from color, so that you can adjust one without affecting the other. Lab is a conversion of the same information to a lightness component L, and two color components - a and b. The human eye can see millions of colors. RGB operates on three channels: red, green and blue. ![]()
