OSA-UCS to DIN99 Lab(DLAB) 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.

DIN99 Lab(DLAB) color space introduction

Also known as the DIN99 Lab(DLAB) color space.There are 3 channels in total,L,range from 0 to 100.a,range from -40.09 to 45.501.b,range from -40.469 to 44.344.
DIN99 Lab, often referred to as DLab, is a color space derived from the CIE L*a*b* color space. It was developed based on the DIN99 colorimetric system, which is an adaptation of the L*a*b* model to improve perceptual uniformity.
DIN99 Lab color space.
In the DIN99 Lab color space, colors are represented by Lightness (L*99), green-red chromatic component (a*99), and blue-yellow chromatic component (b*99).
DLab is primarily used in fields where more precise perceptual uniformity is required, such as color science and quality control.
The DLab color space is particularly useful in color evaluation and matching due to its perceptual uniformity in representing colors.
