Lurid means shocking or sensational, especially in a way that provokes horror or disgust. It can also describe something that is unnaturally bright or gaudy in color, or a tale or detail that is gruesome or luridly sensational.

If you’d like, I can tailor the definition to a specific context (e.g., a lurid news headline, a lurid description in a novel, or a lurid color in fashion) and provide example sentences.
