Description

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>).
