Use this if you are using igraph from R
This is the ‘PuOr’ palette from http://colorbrewer2.org. It has at most eleven colors.
diverging_pal(n)
n |
The number of colors in the palette. The maximum is eleven currently. |
This is similar to sequential_pal
, but it also puts
emphasis on the mid-range values, plus the the two extreme ends.
Use this palette, if you have such a quantity to mark with vertex
colors.
A character vector of RGB color codes.
Other palettes:
categorical_pal()
,
r_pal()
,
sequential_pal()
