Oklab to HSI Converter - Color Space Converter

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.

HSI color space introduction

Also known as the HSI color space.There are 3 channels in total,hue,range from 0 to 360.saturation,range from 0 to 100.intensity,range from 0 to 255.
Origin: The HSI color space was designed to better match the color perception characteristics of the human eye, suitable for processing color-related information.
Primary Names: HSI, which includes H (Hue), S (Saturation), and I (Intensity) as the three color channels.
Typically expressed as a triplet, for example: hsi(120°, 0.5, 0.75) represents a green hue with medium saturation and high brightness.
Usage Scope: Extensively used in image processing and analysis, such as color segmentation, edge detection, target tracking, etc.
Additionally, HSI can be converted to and from RGB, and while similar to HSV and HSL, in HSI, I (Intensity) represents the overall brightness of the color.
