Smooth refers to a surface that is free from roughness, while flat describes a surface which lacks depth or contour. Even pertains to a surface that is uniform and lacks any variation. These antonyms are important to remember when creating artwork or when describing a particular texture. By using these words, artists and writers can add depth and clarity to their descriptions and convey a precise meaning to their audience.
