If you work summer ball then that can vary. First of all it really depends on who you work for and what are the requirements. My association (assignor and leagues I work for) allows us to wear cream, light blue (with the black collar), black and even red. Of course the nave blue is the default color, but during the summer most people want to wear the other colors. You will also find that many umpires that have experience with college ball in this state try their best not to wear the navy blue. The bottom line check with who will assign you games and buy what is recommended. If you can afford it, buy the colors I just mentioned (I would not buy the red unless it is common where you live). Baseball is the most expensive sport of all so you do not want to just throw money away at equipment you will not use.
