LAB(cielab) to DLCH(DIN99 LCH) 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.

DLCH(DIN99 LCH) color space introduction

Also known as the DLCH(DIN99 LCH) color space.There are 3 channels in total,L,range from 0 to 100.C,range from 0 to 51.484.H,range from 0 to 360.
DIN99 LCH is a color space based on the DIN99 colorimetric system. It's an LCH (Lightness, Chroma, Hue) representation, which is a derivative of the CIELAB color space. The DIN99 system was developed to improve the perceptual uniformity of the LAB color space, making color differences more consistent with human vision.
DIN99 LCH color space.
In the DIN99 LCH color space, colors are represented by Lightness (L*99), Chroma (C*99), and Hue angle (h°99).
DIN99 LCH is commonly used in fields requiring precise color matching and analysis, such as the textile and plastics industries.
The DIN99 LCH color space is widely used in color science and industrial applications due to its perceptual uniformity in representing colors.
