How is something that is 'flamboyant' best characterized?

The term "flamboyant" is best characterized by being elaborately ornamented. It conveys a sense of boldness, showiness, and extravagance, often associated with vivid colors, elaborate designs, or striking appearances. When something is described as flamboyant, it suggests that it stands out and draws attention due to its flashy and ornate qualities. The other options do not align with this definition; for instance, subtle, ordinary, modest, simple, and plain all indicate a lack of ostentation, which is antithetical to the essence of flamboyance. Thus, the correct characterization highlights the vivid and ornate nature that defines flamboyant expressions or styles.
