LAB(cielab) to HCG(HSG) 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.

HCG(HSG) color space introduction

Also known as the HCG(HSG) color space.There are 3 channels in total,hue,range from 0 to 360.chroma,range from 0 to 100.gray,range from 0 to 100.
The HCG color space incorporates elements from the HSL/HSV color models and provides a direct path to grayscale, addressing the issue of maintaining hue and saturation as colors fade to white or black.
Known as the HCG color space.
Colors are represented by hue (H), chroma (C), and gray (G), allowing for a transition to gray scale as the chroma decreases and the gray increases, enabling the color to fade without losing its hue.
The HCG color space is often used in applications such as data visualization where colors may need to be muted or made pastel while still retaining their color identity.
HCG combines the hue and saturation control of HSL/HSV with the concept of gray scale to provide a more flexible way of color fading.
