What does the term pied refer to?

The term "pied" is derived from a description of animals or objects that have patches or spots of different colors, often in bright hues. It is commonly used in contexts such as describing certain birds, like a pied crow or a pied wagtail, which display contrasting sections of color. The emphasis on being "colored differently and brightly" captures the essence of the term, indicating a variety of vibrant colors or patterns rather than a uniform or muted appearance. Thus, the choice accurately reflects the meaning of pied, focusing on the distinctive and varied coloring rather than the monochrome or subtle hues found in other options.
