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)
