UCS(cie1960) to UVW(cieuvw,cie1964) Converter - Color Space Converter

UCS(cie1960) color space introduction

Also known as the UCS(cie1960) color space.There are 3 channels in total, U,range from 0 to 100.V,range from 0 to 100.W,range from 0 to 100.
Developed by the International Commission on Illumination (CIE) in 1960, it was intended to provide a uniform color scale that would more closely align with human vision.
The primary name is CIE 1960 UCS (Uniform Color Scale). It is also referred to as the CIE 1960 (u, v) chromaticity space.
Colors in the CIE 1960 UCS are expressed in terms of chromaticity coordinates 'u' and 'v' derived from the CIE XYZ color space, with the addition of a 'W' coordinate representing the luminance factor.
The CIE 1960 UCS is used for applications where a more perceptually linear color space is useful. It's often used in color research and for specifying the colors of light sources and illuminants.
The CIE 1960 UCS is an intermediate step towards the development of subsequent color spaces that are more perceptually uniform, such as CIELUV and CIELAB.

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.
