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 6 colours from any palette to a continuous scale (6 colours per palette gives nice gradients; more results in more saturated colours. See this color palette for more colors.. 2. The Layers. The layers in ggplot2 are also called 'geoms'.Once the base setup is done, you can append the geoms one on top of the other.
