YCgCo to Oklab Converter - Color Space Converter

YCgCo color space introduction

Also known as the YCgCo color space.There are 3 channels in total, Y,range from 0 to 1.Cg,range from -0.5 to 0.5.Co,range from -0.5 to 0.5.
Origin: The YCgCo color space was designed for digital video processing to provide a simple and reversible color transformation method, serving as an approximation of the YCbCr color space.
Primary Names: YCgCo color space, where 'Y' represents the luminance component, 'Cg' stands for the green difference component, and 'Co' represents the red-blue difference component.
Typically expressed as a triplet, for example: YCgCo(0.5, -0.25, 0.25) represents a color with specific luminance and chromatic differences.
Usage Scope: Mainly used in image coding and digital video processing, for example, it is applied in encoding standards such as JPEG XR and H.264/MPEG-4 AVC.
Additionally, due to the simple conversion process of YCgCo, it supports efficient hardware implementation and can be losslessly transformed back to the RGB format.

Oklab color space introduction

Also known as the Oklab color space.There are 3 channels in total,L,range from 0 to 1.a,range from -0.4 to 0.4.b,range from -0.4 to 0.4.
OKLab is a perceptually uniform color space developed by Björn Ottosson, designed as a simple and computationally efficient color space that closely aligns with human vision.
OKLab color space.
In the OKLab color space, colors are represented by Lightness (L), green-red chroma component (a), and blue-yellow chroma component (b).
OKLab is commonly used for tasks where color difference is important, such as color grading, graphic design, and image processing.
Due to its perceptual uniformity and simplicity in computation, OKLab is particularly useful in color editing and image analysis.
