Colours

Picking colours for plots

See https://www.perceptualedge.com/articles/b-eye/choosing_colors.pdf for an interesting discussion on picking colours for data visualisation.

Also check the ggplots docs for colour brewer and the Colour Brewer website.

Named colours in R

print.col <- Vectorize(function(col){
  rgb <- grDevices::col2rgb(col)
  sprintf("<span style='padding:1em; background-color: rgb(%s, %s, %s);'>&nbsp;</span> %s \n\n", rgb[1], rgb[2], rgb[3], col,  rgb[1], rgb[2], rgb[3])
})
