What is Brewer palette?
Sequential palettes are suited to ordered data that progress from low to high. Lightness steps dominate the look of these schemes, with light colors for low data values to dark colors for high data values.
What color is Col?
The reason is simple. In R, the color black is denoted by col = 1 in most plotting functions, red is denoted by col = 2 , and green is denoted by col = 3 . So if you’re plotting multiple groups of things, it’s natural to plot them using colors 1, 2, and 3.
