  "Description": "Carries out mapping between assorted color spaces\nincluding RGB, HSV, HLS, CIEXYZ, CIELUV, HCL (polar CIELUV),\nCIELAB, and polar CIELAB. Qualitative, sequential, and\ndiverging color palettes based on HCL colors are provided along\nwith corresponding ggplot2 color scales. Color palette choice\nis aided by an interactive app (with either a Tcl/Tk or a shiny\ngraphical user interface) and shiny apps with an HCL color\npicker and a color vision deficiency emulator. Plotting\nfunctions for displaying and assessing palettes include color\nswatches, visualizations of the HCL space, and trajectories in\nHCL and/or RGB spectrum. Color manipulation functions include:\ndesaturation, lightening/darkening, mixing, and simulation of\ncolor vision deficiencies (deutanomaly, protanomaly,\ntritanomaly). Details can be found on the project web page at\n<https://colorspace.R-Forge.R-project.org/> and in the\naccompanying scientific paper: Zeileis et al. (2020, Journal of\nStatistical Software, <doi:10.18637/jss.v096.i01>).",
