CIELAB色彩空间（英語：CIELAB color space）又寫為L*a*b*，是國際照明委員會（縮寫為CIE）在1976年定義的色彩空間。它將顏色用三個值表達示：「L*」代表感知的亮度、「a*」和「b*」代表人類視覺的四種獨特顏色：紅色、綠色、藍色和黃色。

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 …

lab颜色模型弥补了rgb和cmyk两种色彩模式的不足。 它是一种设备无关的颜色模型，也是一种基于生理特征的颜色模型。 Lab是由一个亮度通道（channel）和两个颜色通道组成的。

2018年9月4日 · Lab是一种色彩空间，也即一种颜色模型，是在1931年国际照明委员会(CIE)制定的颜色度量国际标准的基础上建立的，在1976年又经修订并被命名为CIELab.它包括人眼所能看到的所有的颜色（可见光谱），所以也是目前为止色域最宽的色彩空间，其每一组色值对应一种 ...

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.

lab颜色模型弥补了rgb和cmyk两种色彩模式的不足。 它是一种设备无关的颜色模型，也是一种基于生理特征的颜色模型。 Lab颜色模型由三个要素组成，一个要素是亮度（L），a 和b是两个颜色通道。

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.

Understanding LAB color values is essential for anyone involved in the printing industry. By providing a standardized and perceptually accurate way to define colors, LAB ensures consistency, quality, and precision in printed materials.

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).

The CIELAB color space, also known as the LAB color space, specifies colors along three separate scales – Lightness (L), Red – Green (A), and Yellow – Blue (B). Designed to be an approximation of how the human eye sees, the CIELAB color space has a variety of uses for a …
