The inlcolor package is an R package that provides access to a variety of color schemes. It is designed to support packages and scripts written by researchers at the United States Geological Survey (USGS) Idaho National Laboratory Project Office (INLPO). The package has a simple and consistent API, and supports qualitative, diverging, and sequential color schemes. It also supports combining color palettes using a hinge location, simulates color blindness, and has few dependencies. The goal of inlcolor is to be a single comprehensive collection of color schemes for maps and graphs in INLPO publications.


To install the current release of the package from CRAN you can use the following command in R:


To install the package along with its dependencies, which are required to run examples in the package help documentation and simulate partial-color blindness, run:

install.packages("inlcolor", dependencies = TRUE)

To install the development version of the package, you need to clone the repository and build from source, or run the following commands:

if (!requireNamespace("remotes")) install.packages("remotes")
  repo = "inl/inlcolor@develop",
  auth_token = Sys.getenv("GITLAB_PAT"),
  host = "",
  dependencies = TRUE


The package provides two main functions for interacting with color palettes:
