paletteer: Hundreds of color palettes in R

Looking for just the right colors for your data visualization?

I often cover tools to pick color palettes on my website (e.g. here, here, or here) and also host a comprehensive list of color packages in my R programming resources overview.

However, paletteer is by far my favorite package for customizing your colors in R!

The paletteer package offers direct access to 1759 color palettes, from 50 different packages!

After installing and loading the package, paletteer works as easy as just adding one additional line of code to your ggplot:

install.packages("paletteer")
library(paletteer)

install.packages("ggplot2")
library(ggplot2)

ggplot(iris, aes(Sepal.Length, Sepal.Width, color = Species)) +
  geom_point() +
  scale_color_paletteer_d("nord::aurora")

paletteer offers a combined collection of hundreds of other color palettes offered in the R programming environment, so you are sure you will find a palette that you like! Here’s the list copied below, but this github repo provides more detailed information about the package contents.

Overview of built-in colors in R

Most of my data visualizations I create using R programming — as you might have noticed from the content of my website.

Though I am colorblind myself, I love to work with colors and color palettes in my visualizations. And I’ve come across quite some neat tricks in my time.

For instance, did you it’s super easy to create a reproducible though custom color palette? Or that there’s a quick reference card for ggplot2’s built-in colors? Or, and this is this blog post’s main subject, that you can access all built-in base colors using colors()!

This last trick, I learned in this recent blog post I came across, by Chisato. She explored all colors() base R incorporates, using the new ggforce and ggraph packages (thank you Thomas Lin Petersen!). Her exploration resulted in some nice visual overviews, which you can view in more detail in the original blog here.

Colors() that have at least 5 colors in their family

100 amazing color palettes including their Hex codes

TJ Mahr hinted to this Canva webpage on Twitter. It contains 100 beautiful color palettes including their hexadecimal color codes. For instance, these three below.

The great thing is that these color palettes are include in the ggthemes package in R. Hence, the following code uses this Nightlife palette directly in an R script, resulting in the plot below.

library(ggplot2)
library(ggthemes)

ggplot(mtcars) +
  aes(x = disp, y = mpg, color = factor(cyl)) +
  geom_point(size = 6) +
  ggthemes::scale_color_canva(palette = "Nightlife")

What’s your favorite color palette among these 100?

Google for Colors

Picular.co calls itself Google, but for colors on its website. And not without good reason. On the site, you type in a color association (e.g., forest green), and it provides you an palette overview of associated colors and their hexadecimal (Hex) codes.

I don’t precisely know how it works, but it seems to work quite well!

What to consider when choosing colors for data visualization, by DataWrapper.de

Lisa Charlotte Rost of DataWrapper often writes about data visualization and lately she has focused on the (im)proper use of color in visualization. In this recent blog, she gives a bunch of great tips and best practices, some of which I copied below:

color in data vis advice — Gradient colors can be great to show a pattern but, for categorical data, it is often easier to highlight the most important values with colored bars, positions (like in a dot plot) or even areas. [https://blog.datawrapper.de/colors/]

You can find additional useful tips in the original DataWrapper blog.
