 #' Create colour scales based on ColorBrewer colours.
 #' 
-#' ColorBrewer provides sequential, diverging and qualitative colour schemes which are particularly suited and tested to display discrete values (levels of a factor) on a map. ggplot2 can use those colours in discrete scales. It also allows to smoothly interpolate the colours to a continuous scale, although the original colour schemes (particularly the qualitative ones) were not intended for this. The perceptual result is left to the appreciation of the user.
