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.

LABh(hunter-lab,hlab) color space introduction

Also known as the LABh(hunter-lab,hlab) color space.There are 3 channels in total,lightness,range from 0 to 100.a,range from -128 to 128.b,range from -128 to 128.
Developed by Richard S. Hunter in the 1940s as a color scale based on opponent-color theory. It is an adaptation of the CIE XYZ color space to be more perceptually linear.
Often referred to as Hunter Lab, or Lab Hunter.
Colors in the Hunter Lab color space are expressed through three coordinates: L (for lightness), a (red/green value), and b (blue/yellow value). These are calculated from CIE XYZ using Hunter's specific equations.
Hunter Lab is used in various industries for color matching, quality control, and other applications where a perceptually linear space is beneficial for color difference measurement.
Although similar to CIELAB, the Hunter Lab color space is used less frequently in contemporary applications. However, it remains significant in industries that adopted it early on and continue to rely on its specific color-rendering properties.
