REC.2100-PQ to HCG(HSG) Converter - Color Space Converter

REC.2100-PQ color space introduction

Also known as the REC.2100-PQ color space.There are 3 channels in total, Red,range from 0 to 1.Green,range from 0 to 1.Blue,range from 0 to 1.
Rec. 2100 PQ (Perceptual Quantizer) is one of the HDR standards developed under ITU-R BT.2100, designed to accurately represent a wide range of brightness levels from deep blacks to intense highlights, far exceeding what standard dynamic range (SDR) can offer.
Rec. 2100 PQ color space.
In the Rec. 2100 PQ color space, colors are represented through Red (R), Green (G), and Blue (B) channels, designed based on the human visual system to ensure that each increment in brightness is perceived uniformly.
Rec. 2100 PQ is primarily used in HDR video production and playback that require a wide range of brightness representation.
Rec. 2100 PQ is widely used in professional video production and high-end television playback due to its precision in representing HDR content and uniform perceptual brightness increments.

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.
