Maybe this synthesis of both replies can help you:
library(RColorBrewer)
bl5 <- brewer.pal(5, "Blues")
mypal <- colorRampPalette(bl5)
library(spatstat)
data(longleaf)
Z <- smooth.ppp(longleaf)
plot(Z)
plot(Z, col=mypal(12))
#or
plot(Z, col=rev(mypal(12)))

This is what I did, but I couldn't find, and still can't find,
anything in the help for plot.im or topo,colors that explains how to
change the colours to graduated blue, am being really dim here.
However, in another post it was suggested I use rColorbrewer to set
up the colours , but it worries me that I cannot find the bit in the
help you have sent me to.
