鮮やかあざやかJLPT N1approx.Common
na-adjectiveCovers the vivid, brilliant side of 'vibrant': colors, hues, or visual scenes that are bright, clear, and striking. It is about visual intensity rather than liveliness, so it is not the natural choice for an energetic person.

The moon was shining brightly.

Use 「みずみずしい」 for the lively, fresh, youthful sense of 'vibrant' in people or things; use 「鮮やか」 for the vivid, bright, brilliant sense, chiefly of colors or images.
