11.27 Colour Names

20200608

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

length(colours())

## [1] 657

colours() %>% sample(12)

##  [1] "coral4"         "lightsalmon"    "gray53"         "red3"          
##  [5] "grey56"         "peru"           "khaki1"         "firebrick2"    
##  [9] "aquamarine"     "gray52"         "paleturquoise4" "gray71"

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)
