Dark-and-light spots can refer to various patterns and shapes which appear to be alternating between contrasting colors. Common synonyms for this phrase include mottled, speckled, dappled, and blotched. Another option is variegated, which describes a color scheme that is composed of variously colored patches or streaks. Flecked can also be used to describe an object that is covered with small, irregularly shaped spots or specks. If the dark-and-light spots are arranged in a more uniform pattern, they might be called spotted or stippled. Finally, marbled can be used to describe a pattern that resembles swirls of contrasting colors, like those seen in marble countertops or floors.
