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
python -m pip install ./python-mie

To remove:

python -m pip uninstall pymie

You might want to first set up a conda environment (using the included environment.yml file) and install the pymie package in that environment.

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).
