华丽 (huá lì) describes something rich, ornate, and showy in an elegant way — like palace decorations, formal dresses, or elaborate writing. It emphasizes lavish, refined beauty, unlike 豪华 (háo huá) which focuses on luxury and expense, or 辉煌 (huī huáng) which suggests glory and brilliance (e.g., achievements). 艳丽 (yàn lì) is more about bright, striking colors and can carry a negative connotation of being gaudy.
