I decided to do a Nike MLB Uniform Refresh, some teams will get total rebrands, some will have altered colors, some will have new alternates, or get new throwbacks. Visit my Behance to see my other sports designs: https://www.behance.net/ianrasovsky
For the diamondbacks, I updated the home and away uniforms by replacing the sand accents with teal, solidifying teal as their new tertiary color. I also added their purple alternate from 1998 on the new Nike MLB teamplate. I also created a new home cap, that replaced the sand in the diamonbacks's "A" logo.
