-## Contribute
 
-Please fork, add color space with basic _conversions_ to/from XYZ or RGB and _tests_.
-The goal of the project is the most complete set of color spaces with minimal uniform API.
+## Purpose
 
+A complete collection of color spaces with minimal consistent and clean API, verified formulas and cases.
+While alternatives focus on digital color spaces, this project takes broader perspective, including historical / multidisciplinary spaces.
+A side effect is verifying and correcting papers.
 
 ## Credits
 
-Thanks to all scientists, who devoted their time to color research and conveyed their knowledge, for now we can use their formulas and code.
+Thanks to all who contribute to color science – researchers, scientists, color theorists, specifiers, implementors, developers, and users.
