R package: RColorBrewer

RColorBrewer can be used to create colorful graphs with pre-made palettes that consist of 8 to 12 colors. In order to create more colors in a palette, colorRampPalette can be used.

There are three types of palettes:

qualitative: different hues emphasize different classes.
diverging: extrem (low and high) values are colored with dark, average values with ligher colors.
sequential: progress from light colors for low values to dark colors for high values.

RdYlBu

A particular beautiful palette seems to be RdYlBu:

library(RColorBrewer)
library(raster)

palette = brewer.pal(11,'RdYlBu');

grid <- raster(ncols=11, nrows = 1, xmn=1, xmx=11, ymn=1,ymx=2);

values(grid) <- 1:11

par(mar=rep(0.5, 4))
plot(grid, col=palette, legend=FALSE, axes = 0, box=FALSE)
