Summary
A new working paper describes the new and much improved color palette functionality in base R since version 4.0.0, including the functions palette.colors() and hcl.colors() for providing more than 100 well-established palettes with improved perceptual properties.

Fact

  • 🎨 The new and much improved default color palette in base R provides a selection of more than 100 well-established palettes via the functions palette.colors() and hcl.colors().
  • 🌈 The hcl.colors() function systematically varies the perceptual hue, chroma, luminance properties in the palette for ordered or numeric data with central value and for data with a high-low scale.
  • 🎨 The palette.colors() function provides a range of popular qualitative palettes for categorical data.
