structural-color

Python package for modeling structural color in colloidal systems. See the tutorial Jupyter notebook (tutorial.ipynb) for instructions on using the package.

Requires the python-mie (pymie) package for Mie scattering calculations. To install:

git clone https://github.com/manoharan-lab/python-mie.git
pip install ./python-mie

To remove:

pip remove pymie

You might want to first set up a virtual environment and install the pymie package there.

The original code was developed by Sofia Magkiriadou (with contributions from Jerome Fung and others) during her research [1,2] in the Manoharan Lab at Harvard University. This research was supported by the National Science Foundation under grant number DMR-1420570 and by an International Collaboration Grant (Grant No. Sunjin-2010-002) from the Korean Ministry of Trade, Industry & Energy of Korea. The code has since been updated. It now works in Python 3, and it can handle quantities with dimensions (using pint).
