I created a data map of sales from my best twenty zip codes and colored coded those twenty zip codes based on total sales.

I imported the data.

Problem: All the zip codes that I had no imput data on was defaulted to a off green color. What I would like is to change that color to white to offer a better contrast to my best twenty zip codes (still having the outlines of all the zip codes).

Is there a way to change the default color after crreating a data map?

Thanks for any help.
