Fabio Crameri's Colour Schemes
Crameri (2018) offers carefully chosen schemes, ready for mapping data, with colours that are:
- Perceptually uniform,
- Perceptually ordered,
- Colour vision deficiency friendly,
- Readable as black and white print,
- Citable & reproducible.
All the scales presented in Crameri (2021) are implemented here, for use with base R graphics or ggplot2.
