Non-transitory computer-readable medium and method of generating embroidery data

A method of generating embroidery data comprising:

• obtaining image data representing an image;
• obtaining a plurality of thread colors as available colors to be used for sewing an embroidery pattern;
• setting a first color representing a target area in the image;
• in a case where at least one color is assigned from the available colors as a color representing the target area, selecting a color close to the first color when combined with the at least one color assigned, from the available colors, as a candidate;
• determining whether a difference between color information representing the at least one color assigned and color information representing the candidate is smaller than a threshold value;
• in a case where the determining determines that the difference is smaller than the threshold value, adding the candidate to the at least one color assigned;
• in a case where a plurality of colors are assigned from the available colors each as a color representing the target area and the candidate is represented by color information having a smaller difference from each of the plurality of colors assigned than the threshold value, adding the candidate to the target area;
• generating the embroidery data associating thread color data with position data, the thread color data representing a color selected from the at least one color assigned, the position data specifying a position to sew with a thread having the color represented by the thread color;
• and
• embroidering the embroidery pattern of the image onto a workpiece based on the generated embroidery data.
