Aesthetic senses involve the ability to perceive beauty and appreciate art, design, and other forms of creativity. The antonyms for aesthetic senses would be words like dull, ugly, plain, unattractive, and mundane. These words suggest a lack of interest or appreciation for beauty and art, and a preference for practicality over aesthetics. Someone who lacks aesthetic senses may view art as a waste of time or money and may not see the value in creating or appreciating beauty in their environment. However, it should be noted that aesthetics is a subjective concept, and what one person finds beautiful, another may find unappealing.
