Generate a palette of tints, shades or both from a single colour.
tinter
provides a simple way to generate monochromatic palettes.
Easily define:
steps
).crop = 1
eliminates black and white).adjust
).library(tinter)hex <- "#a6c2d8"
tinter(hex)#> [1] "#EDF2F7" "#DBE6EF" "#C9DAE7" "#B7CEDF" "#A6C2D8" "#849BAC" "#637481"#> [8] "#424D56" "#21262B"
tinter(hex, direction = "tints")
tinter(hex, steps = 10)
tinter(hex, steps = 10, crop = 7)
tinter(hex, steps = 10, crop = 7, adjust = 0.4)
library(ggplot2)library(sf)nc <- st_read(system.file(package = "sf", "shape/nc.shp"))ggplot(data = nc) +geom_sf(aes(fill = AREA), colour = "white", lwd = 0.05) +# colours from tinterscale_fill_gradientn(colours = tinter(hex)) +theme_void() +coord_sf(datum = NA)
tinter
just simplifies a task usually done with grDevices
. It’s
default is to remove black and white from the palette.
