YCgCo to HCG(HSG) 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.

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.
