They want to be able to differentiate denominations by color (e.g. orange for tens, green for twenties, blue and red for fifties.)

Indeed they do, as they are presently all the same. I thought you said they were already different.

Today, tens are orange, twenties are green, and fifties are blue and red. They would need to add color to fives and ones and hundreds, but I am assuming that change is already in the pipeline and will show up eventually.
