0. Basic Information

To use colorblind-friendly palettes in R, you mainly need the following packages. Be sure that we checked the plots with these packages before saving the plots. Thank you!

1. colorbindr

Simulate colorblindness in production-ready R figures. Written by Claire D. McWhite and Claus O. Wilke.

Official repo: https://github.com/clauswilke/colorblindr

1.1 Installation

remotes::install_github("wilkelab/cowplot")
install.packages("colorspace", repos = "http://R-Forge.R-project.org")
remotes::install_github("clauswilke/colorblindr")

It could also be installed with: (but you need to install pakfirst.

pak::pkg_install("clauswilke/colorblindr")

1.2 Demo

It is easy to follow the official document, first make a ggplot object like:

library(ggplot2)
fig <- ggplot(iris, aes(Sepal.Length, fill = Species)) + geom_density(alpha = 0.7)
fig

Then we could use this package to check in different simulations:

library(colorblindr)

Loading required package: colorspace

cvd_grid(fig)

It is also possible to inspect it in the interactive app, I just show the script, it will not open a tab for readers.

view_cvd(fig) # starts the interactive app

2. colorblindcheck

Check Color Palettes for Problems with Color Vision Deficiency

Official repo: https://github.com/Nowosad/colorblindcheck

2.1 Installation

install.packages("colorblindcheck")

2.2 Demo

library(colorblindcheck)
