mottle

Imagine an autumn leaf, not evenly red or yellow, but marked with patches of different colors. That is the kind of look this word describes. It means to cover something with spots, blotches, or uneven areas of color. You might notice it on skin when someone is very cold, or on the faded paint of an old barn. It is not solid and smooth in color; it looks mixed and patchy instead.

The word often brings to mind natural patterns, like the wings of a butterfly or the shell of an egg. It is mainly about appearance: colors or tones that do not spread evenly, but gather in irregular marks. Think of watercolor paint drying in soft patches instead of one flat shade.

To mottle means to mark something with spots, blotches, or patches of different color, so the surface looks uneven rather than plain or uniform. The effect can be slight or strong, but it usually suggests irregular color spread across the surface. For example, an old ceramic vase may become mottled with age, showing areas of fading or discoloration.

This kind of pattern appears often in nature. Bird eggs, stone, leaves, animal fur, and butterfly wings can all show it. It also appears in medicine, especially in the phrase "mottled skin," when the skin looks patchy because of cold, poor circulation, or illness. In art or design, someone may also mottle paint or glaze on purpose to create texture and variation.

The word is used mostly in a literal, visual sense. It usually describes how something looks, not how it feels or sounds. Figurative use is possible, but it is uncommon and much less important than the basic meaning of a patchy, spotted appearance.

The word is related to motley, which also carries the idea of mixed colors. In everyday English, though, this word is best understood in a simple way: it describes a surface marked by irregular patches or spots. Whether you are talking about a leaf, a wall, skin, or a painted object, the central idea is always the same: color that appears unevenly in scattered marks.
