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.
install.packages(c("RSurvey", "dichromat")) library(RSurvey)
col <- ChooseColor(col = "#669933")

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

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

The ChoosePalette function may eventually reside in the colorspace package.
