LABh(hunter-lab,hlab) to lms Converter - Color Space Converter

Also known as the LABh(hunter-lab,hlab) color space.There are 3 channels in total, lightness,range from 0 to 100.a,range from -128 to 128.b,range from -128 to 128.

Developed by Richard S. Hunter in the 1940s as a color scale based on opponent-color theory. It is an adaptation of the CIE XYZ color space to be more perceptually linear.

Often referred to as Hunter Lab, or Lab Hunter.

Colors in the Hunter Lab color space are expressed through three coordinates: L (for lightness), a (red/green value), and b (blue/yellow value). These are calculated from CIE XYZ using Hunter's specific equations.

Hunter Lab is used in various industries for color matching, quality control, and other applications where a perceptually linear space is beneficial for color difference measurement.

Although similar to CIELAB, the Hunter Lab color space is used less frequently in contemporary applications. However, it remains significant in industries that adopted it early on and continue to rely on its specific color-rendering properties.

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.
