OSA-UCS to Oklab Converter - Color Space Converter

OSA-UCS color space introduction

Also known as the OSA-UCS color space.There are 3 channels in total, L,range from -10 to 8.j,range from -6 to 12.g,range from -10 to 6.
The OSA-UCS color space was developed by the Optical Society of America in the 1970s with the goal of creating a color space that provided a more uniform appearance than the CIE 1931 XYZ color space.
The OSA-UCS color space, also known as the Optical Society of America Uniform Color Scale.
Colors in the OSA-UCS color space are represented by three parameters: lightness (L), hue (J), and chroma (g).
OSA-UCS is used in the field of visual sciences for the research and precise measurement of color differences due to its uniformity.
The application of the OSA-UCS color space is relatively limited in the commercial sector, primarily because it is more complex to calculate and not as widely used as the CIELAB color space.

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.
