prakriti

30 color palettes for R, each one pulled from an Indian landscape. Himalayan ice. Thar dunes at sunset. Flamingos over the Rann. Bioluminescent shores off Havelock. The autumn chinar canopy in Kashmir.

Palettes come in three types (sequential, diverging, qualitative) and plug straight into ggplot2 with scale_color_prakriti() and scale_fill_prakriti(). They also work fine with base graphics, lattice, or anything else that takes hex codes.

ggplot2

Qualitative palettes default to discrete scales. Sequential and diverging palettes default to continuous. Override with discrete = TRUE/FALSE.

library(ggplot2)

# Categorical
ggplot(iris, aes(Sepal.Length, Petal.Length, color = Species)) +
  geom_point(size = 3) +
  scale_color_prakriti("valley_of_flowers")

# Continuous fill
ggplot(faithfuld, aes(waiting, eruptions, fill = density)) +
  geom_raster(interpolate = TRUE) +
  scale_fill_prakriti("himalaya")

# Diverging
cor_df <- as.data.frame(as.table(cor(mtcars)))
names(cor_df) <- c("x", "y", "r")

ggplot(cor_df, aes(x, y, fill = r)) +
  geom_tile() +
  scale_fill_prakriti("mehrangarh", limits = c(-1, 1))
