+		A Toolbox for Manipulating and Assessing Colors and Palettes //
+		Carries out mapping between assorted color spaces including
+		RGB, HSV, HLS, CIEXYZ, CIELUV, HCL (polar CIELUV), CIELAB, and
+		polar CIELAB. Qualitative, sequential, and diverging color
+		palettes based on HCL colors are provided along with
+		corresponding ggplot2 color scales. Color palette choice is
+		aided by an interactive app (with either a Tcl/Tk or a shiny
+		graphical user interface) and shiny apps with an HCL color
+		picker and a color vision deficiency emulator. Plotting
+		functions for displaying and assessing palettes include color
+		swatches, visualizations of the HCL space, and trajectories in
+		HCL and/or RGB spectrum. Color manipulation functions include:
+		desaturation, lightening/darkening, mixing, and simulation of
+		color vision deficiencies (deutanomaly, protanomaly,
+		tritanomaly). Details can be found on the project web page at
+		https://colorspace.R-Forge.R-project.org/ and in the
+		accompanying scientific paper: Zeileis et al. (2020, Journal of
+		Statistical Software, doi:10.18637/jss.v096.i01).
