CIELABFarbskala

CIELABFarbskala, also known as CIE Lab color space, is a color space developed by the International Commission on Illumination (CIE) in 1976. It is designed to be device-independent, meaning it can be used to describe any color that the human eye can perceive, regardless of the device used to reproduce it. The CIELAB color space is based on the CIE XYZ color space, which is a linear transformation of the RGB color space.

The CIELAB color space is a three-dimensional space with three coordinates: L, a, and b. The L coordinate represents the lightness of the color, with 0 being black and 100 being white. The a coordinate represents the green-red axis, with negative values indicating green and positive values indicating red. The b coordinate represents the blue-yellow axis, with negative values indicating blue and positive values indicating yellow.

The CIELAB color space is perceptually uniform, meaning that the distance between two colors in the space corresponds to the perceived difference between those colors by the human eye. This makes it useful for applications such as color matching, color grading, and color correction. The CIELAB color space is also used in the development of color management systems, which are used to ensure consistent color reproduction across different devices and platforms.

The CIELAB color space is widely used in the printing and graphic arts industries, as well as in the development of digital imaging and color management systems. It is also used in the development of color measurement and color analysis instruments, such as spectrophotometers and colorimeters. The CIELAB color space is supported by many color management software applications, including Adobe Photoshop, CorelDRAW, and GIMP.

In summary, the CIELAB color space is a device-independent, perceptually uniform color space that is widely used in the printing, graphic arts, and digital imaging industries. It is based on the CIE XYZ color space and consists of three coordinates: L, a, and b. The CIELAB color space is supported by many color management software applications and is used in the development of color measurement and color analysis instruments.
