Hi Namrata,
Let's see, where is my crystal ball?

Ah, right. I see that you are referring to an illustration produced by 
an example on a help page. In this illustration the transformation of 
value to color begins with red at the minimum and traverses the red-blue 
range with increasing values. Let us say that your values are contained 
in a vector named "values".

values<-sort(runif(10))
plot(1:10,pch=19,col=color.scale(values,extremes=c("blue","red")))
