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:
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.
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.
