YIQ to HCG(HSG) Converter - Color Space Converter

YIQ color space introduction

Also known as the YIQ color space.There are 3 channels in total, Y,range from 0 to 1.I,range from -0.5957 to 0.5957.Q,range from -0.5226 to 0.5226.
Origin: The YIQ color space was specifically designed for the North American NTSC color television standard to accommodate compatibility between color and monochrome television broadcasts.
Primary Names: YIQ color space, where 'Y' represents the luminance component, 'I' represents the in-phase component, and 'Q' represents the quadrature component.
Typically expressed as a triplet, for example: YIQ(0.5, 0.2, 0.3) represents a color with specific luminance and chromaticity.
Usage Scope: Mainly used in the North American NTSC (National Television System Committee) color television broadcasting system. Although less used in modern digital technology, it played a significant role during the era of analog television.
Additionally, the YIQ color space allows old black and white television receivers to receive and correctly display the luminance signal from color broadcasts without interference from the color information.

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.
