We are capable of printing more than one color on your shirts! There really is almost no limit to how many colors you can use, but keep in mind that the more screens we have to use to make your design the more expensive it can turn out. Also, a simple eye catching design is always better than a busy one.
A good standard is going to be around 3 colors. Any more than that and you will sometimes run into readability issues, more expense, and longer production times.
