Change the color of the Save button

One thing I always have to search for, though I know its general location, is the save button on the main screen for each of my clients when I want to save my work or notes.

It would help greatly if the save button was another color than blue, which seems to be the default color on that tools bar. "Add" is green so is easy to find. if the save button was red, or yellow, or purple, or orange it would be more user friendly, more efficient, and less aggravating.
