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.

XYB color space introduction

Also known as the XYB color space.There are 3 channels in total,X,range from -0.0154 to 0.0281.Y,range from 0 to 0.8453.B,range from -0.2778 to 0.388.
The XYB color space was developed by Google as part of their JPEG XL image format. It's designed to be more efficient for compression and more aligned with human vision than traditional color spaces like RGB.
XYB color space.
In the XYB color space, colors are represented through X, Y, and B channels, with the Y channel representing luminance and X and B channels representing color information.
XYB is primarily used in the JPEG XL image format, suitable for enhancing image compression ratios and quality.
The XYB color space offers higher compression rates while maintaining image quality, making it very effective for web image transmission and storage.
