What are the different color palettes we have in RColorBrewer package?

R ProgrammingServer Side ProgrammingProgramming

The different color palettes can be found by using display.brewer.all() function. Each of the palette has different colors. There are three types of palettes defined with names equential, diverging, and qualitative. They are defined for specific uses as written below −

  • Sequential palettes are suited to ordered data that progress from low to high.
  • Diverging palettes put equal emphasis on mid-range critical values and extremes at both ends of the data range.
  • Qualitative palettes are best suited to representing nominal or categorical data.

Output

We can view an individual color palette by using its name.

Let’s view first palette in Sequential category −

library(RColorBrewer)
display.brewer.pal(n=9,name="YlOrRd")

Output

We can view an individual color palette by using its name.

Let’s view first palette in Diverging category −

library(RColorBrewer)
display.brewer.pal(n=12,name="Set3")

Output

We can view an individual color palette by using its name.

Let’s view first palette in Qualitative category −

library(RColorBrewer)
display.brewer.pal(n=11,name="Spectral")

Output

We can also view hexadecimal color specification of an individual color palette

Let’s view first palette in Sequential category −

library(RColorBrewer)
brewer.pal(n=9,name="YlOrRd")

Output

[1] "#FFFFCC" "#FFEDA0" "#FED976" "#FEB24C" "#FD8D3C" "#FC4E2A"
"#E31A1C"
[8] "#BD0026" "#800026"

We can also view hexadecimal color specification of an individual color palette
