Use 「鮮明」 for clear, distinct images, memories, and impressions, or a clearly drawn stance. For beautiful, vivid color pick 「鮮やか」; for an obvious fact, 「明らか」; for clear criteria or goals, 「明確」. 「クリア」 and 「シャープ」 suit casual talk about pictures; 「明晰」 and 「明瞭」 are written words for clear minds, logic, and sound. The nearest opposite is 「不鮮明」; 「曖昧」 covers vague meanings.
