In order to run the example, we'll need some data, even if it is made
up.
I think you can get the values you want like this:
x<-ceiling(x/100)

If you want to make colors darker, you can do something like this:
darkenColor<-function(col,colorshift=0.75) {
rgbmat<-col2rgb(col)
ncol<-dim(rgbmat)[2]
rgbmat<-rgbmat*colorshift
return(rgb(rgbmat))
}
This will darker your colors toward black.
