Show HN: Simple algorithm and color space to generate diverse skin tones
A developer built a custom color space (TUV) for representing human skin tones in digital art and game development. The methodology involved manually labeling RGB colors as plausible skin tones, applying principal component analysis (PCA) to reshape the dataset, then fitting a spherical equation to the transformed data via guess-and-check in Desmos 3D. The resulting TUV space has three intuitive axes (deep/fair, flushed/ochre, cool/warm) that emerged naturally from PCA. A single R² parameter controls variation range, making it easy to tune for different contexts. Sample Python and JavaScript code is provided for both a color picker UI and a procedural generation algorithm. The post acknowledges significant limitations including subjectivity, display inconsistency, and the inherent complexity of real skin tones.
