LAB(cielab) to LCHuv(cielchuv) 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.

LCHuv(cielchuv) color space introduction

Also known as the LCHuv(cielchuv) color space.There are 3 channels in total,lightness,range from 0 to 100.chroma,range from 0 to 100.hue,range from 0 to 360.
Based on the CIELUV color space, proposed by the International Commission on Illumination (CIE) in 1976, it uses a cylindrical coordinate system instead of a rectangular one.
Commonly known as CIELCH_uv or LCH(uv), abbreviated as LCHuv.
The LCHuv color space expresses colors using lightness (L*), chroma (C*), and hue angle (h°), providing an intuitive way to describe colors.
The LCHuv color space is used in graphic and product design, especially suitable for color comparison and selection, and scenarios that require intuitive manipulation of colors.
The LCHuv color space is user-friendly for color selection based on hue and saturation, suitable for applications where the impact of lighting changes on color appearance needs to be considered.
