HCY to LAB(cielab) Converter - Color Space Converter

HCY color space introduction

Also known as the HCY color space.There are 3 channels in total, hue,range from 0 to 360.chroma,range from 0 to 100.luminance,range from 0 to 255.
The HCY color space represents colors in terms of hue, chroma (colorfulness relative to brightness), and luma (brightness or luminance), offering an alternative to color spaces like HSL and HSV.
Known as the HCY color space.
Colors are defined by hue (H), chroma (C), and luma (Y), with luma (Y) being a representation of brightness that corresponds more closely to human visual perception.
The HCY color space is often used in applications where the perception of color brightness is important, such as video and image processing, and user interface design.
Compared to HSL or HSV, HCY offers a representation of colors that aligns more with human perception of brightness, especially effective during color transformation and adjustment.

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.
