LAB(cielab) to REC.2020 Converter - Color Space Converter

LAB(cielab) color space introduction

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.

REC.2020 color space introduction

Also known as the REC.2020 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. 2020, also known as BT.2020, is a color space defined by the International Telecommunication Union (ITU) for Ultra High Definition Television (UHDTV). It offers a wider color gamut compared to the traditional Rec. 709 used in standard high-definition television.
Rec. 2020 color space.
In the Rec. 2020 color space, colors are represented through Red (R), Green (G), and Blue (B) channels, with a wider gamut than Rec. 709.
Rec. 2020 is primarily used for 4K and 8K UHDTV formats, allowing for the display of more vivid and lifelike colors.
Rec. 2020 color space is particularly suitable for high-end televisions and video production, offering a richer visual experience due to its support for a broader range of colors.
