PyFCS GUI: A new visualization and interaction framework for fuzzy color spaces Vazquez-Conejo, Rafael Tejada Casado, María de la Natividad Herrera Maldonado, Luis Javier Ghinea, Razvan Ionut Soto Hidalgo, José Manuel Python Fuzzy colors Open-source A new graphical user interface (GUI) has been developed as an extension to the open-source PyFCS library for constructing and analyzing fuzzy color spaces. This GUI improves usability and accessibility by allowing users to generate fuzzy color spaces from palettes or images, visualize them interactively in 3D, and perform advanced color mapping. Parametric controls enable users to explore various levels of generalization and specificity in the color modeling process. The resulting fuzzy color spaces can be exported in reusable formats to promote reproducibility. This extension significantly enhances the practical applicability of fuzzy color models, providing a versatile tool for both scientific research and artistic or perceptual analysis. 2025-09-22T08:04:54Z 2025-09-22T08:04:54Z 2025-09 journal article Vazquez-Conejo, R., Tejada-Casado, M., Herrera, L.
