YIQ to Oklab Converter - Color Space Converter

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.

Oklab color space introduction

Also known as the Oklab color space.There are 3 channels in total,L,range from 0 to 1.a,range from -0.4 to 0.4.b,range from -0.4 to 0.4.
OKLab is a perceptually uniform color space developed by Björn Ottosson, designed as a simple and computationally efficient color space that closely aligns with human vision.
OKLab color space.
In the OKLab color space, colors are represented by Lightness (L), green-red chroma component (a), and blue-yellow chroma component (b).
OKLab is commonly used for tasks where color difference is important, such as color grading, graphic design, and image processing.
Due to its perceptual uniformity and simplicity in computation, OKLab is particularly useful in color editing and image analysis.
