Within the base package collection, see
?colorRamp and ?colorRampPalette
Then
or.to.blue<-colorRampPalette(c("orange","green","blue")) #green
included to avoid muddy blues
plot(df$X, df$Y,type="n")
text(df$X, df$Y, labels=df$Z,
col=or.to.blue(length(df$Z))[rank(df$Z)])

(assuming that it is a 100x1000 image), for each pair
of your (x,y) you
Dear Contributors:
I have the next matrix:

8 4 876
9 6 249
10 3 14
I want to order the matrix from bigest Z (1110) to lower Z (14).
