Colors are mysterious business and choosing the right color or color palette for an R graphics can sometimes be a chore. To alleviate this burden, I present two functions for choosing color values.
To access these functions install the RSurvey package and its dependencies:
repo <- "http://cran.us.r-project.org" install.packages("RSurvey", repos = repo, dependencies = TRUE, type = "both")
col <- RSurvey::ChooseColor(col = "#669933")

Choose Color Palette
The second function, choose_palette (source), calls upon a GUI for choosing a color palette in the HCL (Hue, Chroma, and Luminance) color space (fig. 2).
pal <- colorspace::choose_palette(terrain_hcl)

An example graphic accompanies the GUI and may be used to evaluate the robustness of individual color schemes (fig. 3).
