LAB(cielab) to Oklch 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.

Oklch color space introduction

Also known as the Oklch color space.There are 3 channels in total,Lightness,range from 0 to 1.Chroma,range from 0 to 0.4.Hue,range from 0 to 360.
The OKLCH color space is derived from the OKLab color space, providing a cylindrical representation similar to LCH, but based on the more perceptually uniform OKLab color model.
OKLCH color space.
In the OKLCH color space, colors are represented by Lightness (L), Chroma (C), and Hue angle (H).
OKLCH is commonly used for tasks requiring a perceptually linear color space, such as color grading and graphic design.
OKLCH color space is suitable for advanced color editing and design tasks due to its perceptual uniformity.
