This open access book builds upon the conceptual foundations established in the first part, presenting practical methods, tools, and workflows for studying and communicating colour in cultural heritage. Developed within the Horizon Europe project PERCEIVE, this second volume examines how scientific analysis, digital reconstruction, and interactive design can be integrated into reproducible workflows. It documents the operational frameworks, technological infrastructures, and design resources developed to study, model, visualise, and communicate colour change across diverse heritage collections. Structured around three complementary chapters (scientific modelling of colour change, digital tools and services for knowledge sharing, and design resources for interactive experiences) the book presents advanced workflows, AI-assisted methods, FAIR data infrastructures, and participatory exhibition prototypes. Case studies range from ancient polychromy and paintings to textiles, photography, and born-digital art, demonstrating approaches to make colour research accessible and transparent for both specialists and broader audiences. Grounded in principles of care, authenticity, and participation, Chromatic Visions II addresses digital heritage as both a technical and relational practice. The book provides researchers, conservators, curators, designers, and museum professionals with methods and frameworks for interdisciplinary approaches to the digital study and communication of coloured collections.
