Colour Names

20200608

R provides a collection of predefined named colours as returned by grDevices::colours():

length(colours())

## [1] 657

colours() %>% sample(12)

##  [1] "darkorchid3"    "darkgoldenrod4" "lightblue"      "lightskyblue1" 
##  [5] "darkslategray"  "grey69"         "grey76"         "mediumpurple1" 
##  [9] "limegreen"      "darkturquoise"  "gray3"          "ivory3"

Colours can be selected using epitools::colors.plot() with locator=TRUE to display a plot containing all of the named colours. Multiple clicks with the left mouse button on colours (we hear a beep for each click) will return the colour names.

as.character(colors.plot(locator=TRUE)$color.names)
