title: 'palettecore: Derive, Optimise and Audit a Scientific Colour Palette from One
  Seed Colour'
version: 0.2.2
doi: 10.32614/CRAN.package.palettecore
abstract: Generates sequential, diverging and categorical colour palettes from a single
  seed colour in OKLCH with CIEDE2000 spacing, and audits every palette under simulated
  colour-vision deficiency, greyscale conversion, sRGB gamut and WCAG contrast. Colour-vision
  deficiency is simulated at severity 1.0 with the model of Machado, Oliveira and
  Fernandes (2009) <https://doi.org/10.1109/TVCG.2009.113>; the design rationale follows
  Crameri, Shephard and Heron (2020) <https://doi.org/10.1038/s41467-020-19160-7>.
  Mirrors the 'Python' reference implementation maintained in the same repository
  and is validated against shared parity fixtures. Thresholds are configurable design
  rules, not established accessibility cut-offs.
