It is distinguished from its closely-related counterpart, mold, largely by its color: molds appear in shades of black, blue, red, and green, whereas mildew is white.here are many species of mold. The black mold which grows in attics, on window sills, and other places where moisture levels are moderate often is Cladosporium. Color alone is not always a reliable indicator of the species of mold.
