LAB(cielab) to XYB 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.

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.
