The CIELAB color space, also referred to as L*a*b*, is a color space defined by the International Commission on Illumination (abbreviated CIE) in 1976. [a] It expresses color as three values: L* for perceptual lightness and a* and b* for the four unique colors of …

2018年10月8日 · Learn about L*a*b* color space, color values, CIELAB, and color profiles and how they help us locate, represent, and communicate specific colors.

Convert LAB to RGB. This tool is a free online color converter between two color formats LAB and RGB. The tool is fast and very simple to use.

2024年10月21日 · Lab Color is a more accurate color space. It uses three values (L, a, and b) to specify colors. RGB and CMYK color spaces specify a color by telling a device how much of each color is needed.

2024年2月8日 · One of the choices for measuring color is using lab color space. This space has the same components as others, though it is divided into lightness (L*) and two color components (a* stands for red and green value and b* stands for blue and yellow).

2023年9月4日 · The LAB color, also called CIELAB color space, is a color space that describes all color perceptions visible to the human eye. It was developed by the International Commission on Illumination (CIE) in 1976, and has since been widely used in various applications, especially in the color and digital graphics industry.

CIELAB encompasses the range of human color perception. Through color measurements, CIELAB color space distinguishes color differences with precise accuracy using three color values. This accuracy enables the reproduction of an exact color on a consistent basis.

2022年1月10日 · What is lab color space? Lab color space provides us a way to specify and quantify colors in the digital world that can be understood by our devices. This is a general function of any color space like RGB and CMYK. What makes lab color different from the rest is the fact that its color spectrum is very vast.

2015年3月9日 · The Lab* color space is based on the three attributes of color: hue, saturation and lightness. Hue is the color itself and will change as you go around the Lab* diagram. Saturation is how bright or vivid a color is versus how dull or gray a color is.

In the world of digital color, the LAB color space stands out as a powerful tool for accurate color representation and manipulation. Unlike familiar color models like RGB and CMYK, LAB offers a unique approach to describing colors that closely aligns with human perception.
