LAB(cielab) to UCS(cie1960) Converter - Color Space Converter

LAB(cielab) color space introduction

Also known as the LAB(cielab) color space.There are 3 channels in total, lightness,range from 0 to 100.a,range from -100 to 100.b,range from -100 to 100.
Defined by the International Commission on Illumination (CIE) in 1976, as an improvement and extension of the CIE XYZ color space, designed to be a closer approximation to human visual non-linearity.
Commonly known as CIELAB color space, abbreviated as L*a*b* or Lab.
Lab colors are typically represented by three coordinates: L* for lightness, a* for green to red chromaticity, and b* for blue to yellow chromaticity. They can be algorithmically converted to other color spaces for display or printing on different devices.
The Lab color space is extensively used in color measurement and management, particularly important in fields requiring precise color matching and assessment such as digital printing, photography, image analysis, and industrial color testing.
The advantage of the Lab color space lies in its device independence, allowing for consistent and accurate color conversion across different devices and software.

UCS(cie1960) color space introduction

Also known as the UCS(cie1960) color space.There are 3 channels in total,U,range from 0 to 100.V,range from 0 to 100.W,range from 0 to 100.
Developed by the International Commission on Illumination (CIE) in 1960, it was intended to provide a uniform color scale that would more closely align with human vision.
The primary name is CIE 1960 UCS (Uniform Color Scale). It is also referred to as the CIE 1960 (u, v) chromaticity space.
Colors in the CIE 1960 UCS are expressed in terms of chromaticity coordinates 'u' and 'v' derived from the CIE XYZ color space, with the addition of a 'W' coordinate representing the luminance factor.
The CIE 1960 UCS is used for applications where a more perceptually linear color space is useful. It's often used in color research and for specifying the colors of light sources and illuminants.
The CIE 1960 UCS is an intermediate step towards the development of subsequent color spaces that are more perceptually uniform, such as CIELUV and CIELAB.
