LCHab(cielch,LCH,HLC,LSH) to YIQ Converter - Color Space Converter

LCHab(cielch,LCH,HLC,LSH) color space introduction

Also known as the LCHab(cielch,LCH,HLC,LSH) color space.There are 3 channels in total, lightness,range from 0 to 100.chroma,range from 0 to 100.hue,range from 0 to 360.
Derived from the CIELAB color space, it represents colors in a cylindrical coordinate system.
Commonly known as CIELCH or LCH, also referred to as LCH_ab.
Colors in the LCH color space are expressed using lightness (L*), chroma (C*), and hue angle (H°), providing a more intuitive way of specifying colors compared to the Cartesian coordinates used in CIELAB.
The LCH color space is extensively used in industries and applications where accurate color differentiation is crucial, such as graphic design, printing, and paint manufacturing.
The LCH color space can be more convenient for understanding color relationships and specifying colors in a more perceptual manner.

YIQ color space introduction

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.
