Mold on drywall looks like dark stains or patches and usually covers a high-moisture area. Most often, mold grows in humid or poorly ventilated areas of a home such as bathrooms, basements, kitchens, and laundry rooms.
Exposure to damp and moldy environments may cause a variety of health effects, or none at all. Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin.
Mold can be any color.
While most mold growth is often black, grey, or greenish, it can be brown, purple, orange, pink, yellow, red, white, or even a combination of colors.
