an R color palette for ggplot2 using NOAA Fisheries branding colors

This implements these steps to create a ggplot2 compatible palette according to NOAA Fisheries branding.

To install from Github use the following:

remotes::install_github("nmfs-general-modeling-tools/nmfspalette")
library(nmfspalette)

Extract an interpolated color palette from the default “oceans” palette. You can change the number of colors (10 shown below).

nmfspalette::nmfs_palette("oceans")(10)
#>  [1] "#0093D0" "#007EC1" "#0069B2" "#0055A4" "#005097" "#004B8B" "#00467F"
#>  [8] "#5483A9" "#A9C1D4" "#FFFFFF"

To see the palettes, use the display_nmfs_palette() function.

nmfspalette::display_nmfs_palette("oceans", 4)

nmfspalette::display_nmfs_palette("waves", 4)

nmfspalette::display_nmfs_palette("seagrass", 4)

nmfspalette::display_nmfs_palette("urchin", 4)

nmfspalette::display_nmfs_palette("crustacean", 4)

nmfspalette::display_nmfs_palette("coral", 4)

nmfspalette::display_nmfs_palette("regional web", 6)

nmfspalette::display_nmfs_palette("secondary", 4)

In addition to nmfs_palette and display_nmfs_palette to get in-built palettes, you can extract colors by name. Please see the NOAA Fisheries Branding guide for color names, all spaces are replaced with underscores in the color names.

nmfspalette::nmfs_cols("process_blue")
#> process_blue 
#>    "#0093D0"

To use the palettes with ggplot2, the scale_color_nmfs() and scale_fill_nmfs() functions are provided. If no argument is given to scale_color_nmfs(), a default (“oceans”) is used:

p <- ggplot(iris, aes(Sepal.Width, Sepal.Length, color = Species)) +
     geom_point(size = 4) +
     scale_color_nmfs()
p

scale_fill_nmfs does not have a default and therefore requires a named argument for now, this is an example using the “crustacean” palette

ggplot(mpg, aes(manufacturer, fill = manufacturer)) +
    geom_bar() +
    theme(axis.text.x = element_text(angle = 45, hjust = 1)) +
    scale_fill_nmfs(palette = "crustacean")
