tinter provides a simple way to generate monochromatic
palettes. Easily define:
steps).crop = 1 eliminates black and white).adjust).library(tinter)
hex <- "#335CAC"
tinter(hex)
#> [1] "#D6DEEE" "#ADBDDD" "#849DCD" "#5B7CBC" "#335CAC" "#284989" "#1E3767"
#> [8] "#142444" "#0A1222"
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 = 0.04) +
# colours from tinter
scale_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.
