How to create a graph in base R with multiple shades of a particular color?

To create a graph in base R with multiple shades of a particular color, we can follow the below steps −

• First of all, create color shades using colorRampPalette then plot a graph.
• Use the color shades to create the graph.

Example 1

Create the color shades

Using colorRampPalette function to create the color shades between red and darkred color then creating the plot −

Color<-colorRampPalette(c("red","darkred"))
plot(1:5,col=Color(5),pch=16,cex=2)

On executing, the above script generates the below output(this output will vary on your system due to randomization) −

Example 2

Create the color shades

Using colorRampPalette function to create the color shades between blue and darkblue color then creating the plot −

Color<-colorRampPalette(c("blue","darkblue"))
plot(1:8,col=Color(8),pch=16,cex=2)
