USGS Category CRAN Version pipeline status coverage report


The R package inlcolor provides access to a variety of color schemes. Used to support packages and scripts written by researchers at the United States Geological Survey (USGS) Idaho National Laboratory Project Office (INLPO). Key features of this package are (1) a simple and consistent API, (2) support for qualitative, diverging, and sequential color schemes, (3) support for combining color pallets using a hinge location, (4) simulates color blindness, and (5) has few dependencies. The goal of inlcolor is to be a single comprehensive collection of color schemes for maps and graphs in INLPO publications.


The current release is available on CRAN, which you can install using the following command:


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

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:

A hinge is a dramatic change in the colors at a location appropriate for your data (such as, at sea level). Examples are given in the package help pages. To access these documents, run:
