Qualitative Colour Palettes — pal_qualitative • scwplot

Qualitative (sometimes called categorical) colour palettes are used to encode categorical information that has no meaningful order. For example, car manufacturers or sports teams, without context that specifically indicates some natural order, would be unordered categories. Qualitative colour palettes should include colours that all have similar "perceptual weights", meaning that each colour is clearly distinguishable from each other, but that no colour is significantly more distinct than the rest of the palette.

Usage

pal_qualitative(palette = c("nhs", "scw", "scw_warm"), alpha = 1)

Arguments

palette: Currently there are three qualitative colour palettes available: "scw" (a 5-colour palette that includes SCW Dark Blue, NHS Aqua Green, NHS Blue, and NHS Light Green), "nhs" (a 5-colour palette that includes NHS Blue, NHS Light Blue, NHS Mid Grey, and NHS Dark Blue), and scw_warm (a 6-colour palette that includes NHS Blue, NHS Light Blue, SCW Dark Blue, NHS Orange, and NHS Mid Grey).
