CIEfargemodeller

CIEfargemodeller is an open-source software framework that provides implementations of color models and color appearance concepts based on the standards of the International Commission on Illumination (CIE). It is designed for researchers, product developers, and image-processing workflows that require consistent color management, perceptual evaluation, and reproducible color rendering across devices and media.

The framework offers core components for converting between spectral, device-independent, and device-referenced color representations. It includes tools for computing CIE XYZ, CIE Lab, CIE Luv, and related color spaces, as well as perceptual color difference metrics such as Delta E. It also provides implementations of color appearance models (for example, CAM16 and related variants) and supports spectral data inputs for accurate color rendering.

Architecturally, CIEfargemodeller emphasizes modularity and extensibility. The core library exposes a stable API, while plug-in modules allow alternative data sources, observer/adaptation settings, and rendering backends. The project ships with bindings for Python and C++, test suites, and a lightweight GUI for interactive exploration. It supports common cross-platform environments and standard license terms that encourage collaboration.

Applications include color management for digital imaging pipelines, validation of print and display workflows, color-critical quality control, and research in color science. By providing reference implementations and a shared data model, the framework aims to reduce discrepancies across tools and improve reproducibility in color-related research and industry.

As of its latest releases, CIEfargemodeller is maintained by a community of contributors with emphasis on documentation, interoperability, and compliance with established CIE standards. The project is distributed under an open-source license and welcomes contributions of data sets, perceptual models, and translation layers to broaden its applicability.
