Dear Nooshin,

most attachments will not make it into the list. Please upload it somewhere and link to it instead.
alternatively you could post reproducible code to generate your plot so far.

Hi Nooshin,

Have you tried the RColorBrewer package? 
After loading the package, the following gives you the whole array of available colour palletes.

            

      
      
      
    

        
Then, you can add to your code something like this (I'm using palette "Set3" just as an example):

            

      
      
      
    

        
And:

            

      
      
      
    

        
Colv=NA,scale="column", margins=c(5,10), col=nooshin.col)


Hope this helps.

Jos?

my break is mybreaks <-

with different color.
heat map give me red-orang-yellow.I need 8 different colors.

filled.contour(Nooshin, main="Permeability",color.palette=rainbow)
filled.contour(Nooshin, main="Permeability",color.palette=terrain.colors)
filled.contour(Nooshin, main="Permeability",color.palette=topo.colors)

not quite sure what to do with the heat map, but it has a "col" attribute.
