lms to LAB(cielab) Converter - Color Space Converter

lms color space introduction

Also known as the lms color space.There are 3 channels in total, long,range from 0 to 100.medium,range from 0 to 100.short,range from 0 to 100.
The LMS color space is based on the response of the human eye's cone cells to color, consisting of the responses from three different types of cone cells which are most responsive to long, medium, and short wavelengths of light respectively.
LMS stands for Long, Medium, and Short wavelengths.
The LMS color space typically uses three coordinates to express colors, corresponding directly to the responses of the cone cells. This space is often used to calculate transformations to other color spaces that are perceptually closer to human vision, such as from RGB.
The LMS color space is primarily used in the fields of biology and vision science, particularly for simulating and understanding human visual perception.
Since LMS is based on physiological characteristics, it is not commonly used for practical applications such as image processing or color printing but serves as a research and theoretical model.

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.
