abstract: Color schemes ready for each type of data (qualitative, diverging or sequential),
  with colors that are distinct for all people, including color-blind readers. This
  package provides an implementation of Paul Tol (2018) and Fabio Crameri (2018) <https://doi.org/10.5194/gmd-11-2541-2018>
  color schemes for use with 'graphics' or 'ggplot2'. It provides tools to simulate
  color-blindness and to test how well the colors of any palette are identifiable.
  Several scientific thematic schemes (geologic timescale, land cover, FAO soils,
  etc.) are also implemented.
