Mottles can refer to spots or blotches that appear unevenly over a surface. A few synonyms for the word "mottles" include speckles, flecks, marbling, and dapples. Speckles are small spots that may be randomly scattered across an area, while flecks tend to be larger, more irregular in shape, and often sharply defined against the surrounding area. Marbling refers to the random, sinuous patterns that can be found on various surfaces, while dapples usually refer to the spotted pattern of light and shade that occurs in nature, such as on a forest floor. All these synonyms help to describe the appearance of mottles, which can vary in size, shape, and color.
