CMYK to OSA-UCS Converter - Color Space Converter

CMYK color space introduction

Also known as the CMYK color space.There are 4 channels in total, cyan,commonly referred to as c,range from 0 to 100.magenta,commonly referred to as m,range from 0 to 100.yellow,commonly referred to as y,range from 0 to 100.black,commonly referred to as k,range from 0 to 100.
Source: CMYK is derived from the process of color printing. It's the result of the subtractive process, meaning the colors on the original white paper are achieved by subtracting certain colors from white.
Primary name: CMYK, full name being Cyan Magenta Yellow Key, where 'Key' typically refers to Black.
Usage: CMYK is mainly used for color printing, such as in magazines, brochures, posters, etc. It's also employed in graphic design related to printing.
Additionally, it's important to note that CMYK cannot represent all the colors in the RGB color space, especially those very bright ones. This is called a 'color gamut', and different color spaces have different gamuts. Furthermore, Black (K) is introduced in CMYK because pure CMY color mixing typically cannot produce a true black, but rather a deep brown.

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.
