LABh(hunter-lab,hlab) to YIQ 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 YIQ color space.There are 3 channels in total,Y,range from 0 to 1.I,range from -0.5957 to 0.5957.Q,range from -0.5226 to 0.5226.

Origin: The YIQ color space was specifically designed for the North American NTSC color television standard to accommodate compatibility between color and monochrome television broadcasts.

Primary Names: YIQ color space, where 'Y' represents the luminance component, 'I' represents the in-phase component, and 'Q' represents the quadrature component.

Typically expressed as a triplet, for example: YIQ(0.5, 0.2, 0.3) represents a color with specific luminance and chromaticity.

Usage Scope: Mainly used in the North American NTSC (National Television System Committee) color television broadcasting system. Although less used in modern digital technology, it played a significant role during the era of analog television.

Additionally, the YIQ color space allows old black and white television receivers to receive and correctly display the luminance signal from color broadcasts without interference from the color information.
