UVW(cieuvw,cie1964) to LAB(cielab) Converter - Color Space Converter

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.

Also known as the LAB(cielab) color space.There are 3 channels in total,lightness,range from 0 to 100.a,range from -100 to 100.b,range from -100 to 100.

Defined by the International Commission on Illumination (CIE) in 1976, as an improvement and extension of the CIE XYZ color space, designed to be a closer approximation to human visual non-linearity.

Commonly known as CIELAB color space, abbreviated as L*a*b* or Lab.

Lab colors are typically represented by three coordinates: L* for lightness, a* for green to red chromaticity, and b* for blue to yellow chromaticity. They can be algorithmically converted to other color spaces for display or printing on different devices.

The Lab color space is extensively used in color measurement and management, particularly important in fields requiring precise color matching and assessment such as digital printing, photography, image analysis, and industrial color testing.

The advantage of the Lab color space lies in its device independence, allowing for consistent and accurate color conversion across different devices and software.
