Tools & Services
The COLOURS project delivers a specialised ecosystem of digital tools and services, supporting advanced restoration and conservation practices while opening new possibilities for communicating and engaging with cultural heritage.
Built to advance these practices, the COLOURS toolkit provides high-precision analysis and simulation capabilities tailored to diverse artefacts, from polychrome sculptures to historical films. Fully interoperable with the European Collaborative Cloud for Cultural Heritage (ECCCH), these tools enable real-time interaction with digital twins, supporting decision-making and management while fostering inclusive approaches and ensuring the authenticity of restored colours.
StyleShade3D
Enhancing 3D mesh reconstruction with deep learning segmentation.
StyleShade3D integrates deep learning segmentation into conventional geometry pipelines to generate semantic segmentation atlases, enabling region-aware shading and stylisation.
Why on the ECCCH?The ECCCH provides the infrastructure for storing digital twins, allowing the tool to consume high-quality scans directly from the cloud.
- Automatic 2D semantic atlas creation
- Region-specific material assignment
- Optimised multi-view acquisition

Light Damage Estimator (LDE)
Predicting and mitigating light-induced colour changes in sensitive art.
A decision-support tool that estimates how pigments fade under specific lighting scenarios using spectral power distribution datasets.
Why on the ECCCH?Ensures direct access to digital twins and spectral datasets, enabling collaborative risk management across institutions.
- Pigment fading simulation
- Customisable lighting (LED, Daylight, etc.)
- Safe display threshold definition
