In PNWColors: Color Palettes Inspired by Nature in the US Pacific Northwest

PNW Color Palette Package for R

I am soon moving away from the most beautiful place I will ever live, so I did what any nostalgic nature kid / data science nerd would do and immortalized it in an R color palette package. Now I (and you!) can have the colors of Washington State and the Pacific Northwest live on in our presentation figures forever.

All photos were taken by me in places that I love. The Pantone Studio iPhone app helped me extract colors, and Chroma.js Color Palette Helper helped me adjust values to ensure that all palettes are color-blind safe to be used for attractive and inclusive data viz. Structure of the code was inspired by the wesanderson and LaCroixColoR packages from GitHub. See more examples on twitter.

## Building Palettes 

Use the `pnw_palette()` function to build and view palettes. Inputs are 'name', 'n', and 'type' (continuous or discrete). 'Name' is required. If 'n' is blank, function will assume n is equal to the number of colors in the palette (5-8), but if n > palette length, it will automatically interpolate colors between. If 'type' is missing, the function will assume "discrete" if n < palette length, and "continuous" if n > palette length. 

```r
pnw_palette(name="Starfish",n=7,type="discrete")

pnw_palette("Winter",100)

pnw_palette("Bay",8,type="continuous")

pnw_palette("Moth",12)

Palettes can be easily integrated into Base R imaging or ggplot2.

pal <- pnw_palette("Shuksan",100)
image(volcano, col = pal)

pal=pnw_palette("Lake",5, type = "discrete")
ggplot(diamonds, aes(carat, fill = cut)) +
  geom_density(position = "stack") +
  scale_fill_manual(values=pal)  +
  theme_classic()

pal=pnw_palette("Shuksan2",100)
ggplot(data.frame(x = rnorm(1e4), y = rnorm(1e4)), aes(x = x, y = y)) +
  geom_hex() +
  coord_fixed() +
  scale_fill_gradientn(colours = pal) +
  theme_classic()

  # Or, to switch the order, use rev(), see below
  scale_fill_gradientn(colours = rev(pal))

ggplot(data = iris,aes(x=Petal.Length,y=Petal.Width,color=Species))+
  geom_point(size=2)+
  scale_color_manual(values=pnw_palette("Spring",3))+
  theme_classic()

```r pal <- pnw_palette("Anemone",3) ToothGrowth$dose <- as.factor(ToothGrowth$dose) ggplot(ToothGrowth, aes(x=dose, y=len, fill=dose)) + geom_violin(trim=FALSE)+ geom_boxplot(width=0.1, fill="white")+ labs(title="Plot of length by dose",x="Dose (mg)", y = "Length")+ scale_fill_manual(values=pal)+ theme_classic()

 ```r
library(tidyverse)
library(urbnmapr)
pal <- pnw_palette("Winter",100)
countydata %>%
  left_join(counties, by = "county_fips") %>%
  filter(state_name =="Washington") %>%
  ggplot(mapping=aes(long,lat,group = group, fill = horate)) +
  geom_polygon(color="black",size=.25) +
  scale_fill_gradientn(colours = pal) +
  coord_map(projection="albers",lat0=39,lat1=45) +
  theme(legend.title = element_text(),
        legend.key.width = unit(.5,"in")) +
  labs(fill="Homeownership rate") +
  theme_void()
