3.25 Perception/decoding: Color (4)

• Choosing color schemes
  • Take mappings from data to color that are not just numerically but also perceptually uniform
  • → Don’t pick colors adhoc, e.g., use colorbrewer
• Various R packages provide color schemes: RColorBrewer, ggplot2, ggsci, wesanderson and colorspace.
• Think of the color blind: display.brewer.all(colorblindFriendly = T)
