HCY to YIQ Converter - Color Space Converter

HCY color space introduction

Also known as the HCY color space.There are 3 channels in total, hue,range from 0 to 360.chroma,range from 0 to 100.luminance,range from 0 to 255.
The HCY color space represents colors in terms of hue, chroma (colorfulness relative to brightness), and luma (brightness or luminance), offering an alternative to color spaces like HSL and HSV.
Known as the HCY color space.
Colors are defined by hue (H), chroma (C), and luma (Y), with luma (Y) being a representation of brightness that corresponds more closely to human visual perception.
The HCY color space is often used in applications where the perception of color brightness is important, such as video and image processing, and user interface design.
Compared to HSL or HSV, HCY offers a representation of colors that aligns more with human perception of brightness, especially effective during color transformation and adjustment.

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.
