A thread color registration method of registering a color of a thread spool, the method comprising:

• detecting a two-dimensional code by an image sensor;
• in a registration list storing a first color of a first thread spool, storing a second color of a second thread spool different from the first thread spool, the second color being indicated by the two-dimensional code, the registration list being stored in a memory;
• and
• displaying a list image on a display, the list image indicating registered colors that are a plurality of colors stored in the registration list, the registered colors including the first color and the second color.

A thread color registration system comprising:

• a first thread spool;
• a second thread spool different from the first thread spool, the second thread spool having a two-dimensional code;
• a memory configured to store a registration list for registering colors of threads of thread spools;
• an image sensor;
• a display;
• and
• a processor configured to:
• detect the two-dimensional code by the image sensor;
• in a registration list storing a first color of the first thread spool, store a second color of the second thread spool, the second color being indicated by the two-dimensional code;
• and
• display a list image on the display, the list image indicating registered colors that are a plurality of colors stored in the registration list, the registered colors including the first color and the second color.
