UVW(cieuvw,cie1964) color space introduction

Also known as the UVW(cieuvw,cie1964) color space.There are 3 channels in total, U,range from -134 to 224.V,range from -140 to 122.W,range from 0 to 100.
Developed by the CIE in 1964 as an improvement over the CIE 1960 UCS for better perceptual uniformity across different hues and lightness levels.
It is known as the CIE 1964 (U^*, V^*, W^*) color space, and commonly abbreviated as CIE UVW.
The color in the CIE UVW space is represented by three coordinates: (U^*), (V^*), and (W^*). These are calculated from the XYZ coordinates with a series of transformations intended to achieve a more uniform color space, taking into account the luminance factor.
The CIE UVW color space is used in specialized applications that require a uniform measure of color differences, such as in colorimetry research and the development of color standards.
The CIE UVW color space is less commonly used in practical applications today, having been largely replaced by more advanced color spaces like CIELAB and CIELUV, which offer better perceptual uniformity.

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.
