Which term describes something that is excessively bright and showy?

The term that best describes something that is excessively bright and showy is "garish." This word typically conveys a sense of something being overly bright, flashy, or tastelessly showy, often to the point of being unpleasant or overwhelming. When something is referred to as garish, it suggests a lack of subtlety or restraint, emphasizing its glaring, eye-catching nature.

The other terms provide different meanings. "Subdued" refers to something that is quiet, restrained, or lacking in intensity, which contrasts sharply with the brightness implied by garish. "Muted" implies a softer or more toned-down quality, often describing colors or tones that are less vivid. "Elegant" describes something that is graceful and stylish, typically characterized by simplicity and refinement, which again stands in opposition to the excessive nature of garishness. Understanding these distinctions clarifies why "garish" is the most appropriate choice in identifying something that is excessively bright and showy.
