Hi James, you will receive an eps file. With that file, your printer can make any color changes you will need. I can also do it for you. If you would like just the character with your name etc, I can make you a new version just for your shirts. (no extra charge) I would send it to your private email. Your wife is correct, bright color will get anyone's attention, and with your character too, that is sure to get people talking. It's my pleasure and it's always a bonus when the contest holder asks questions and give feedback. Thank you!!! Let me know if I can answer any other questions or make anymore changes don't hesitate to ask!
