7 Common Types of Mold (by Color)

7 Common Types of Mold (by Color)

Hundreds of thousands of types of mold exist, but knowing these 7 common types will help you defend your home.

Mold is one of the major concerns for homeowners, especially in humid, wet areas. Besides geographical location, kitchens and bathrooms are also likely places for unwanted mold growth. A common misconception about mold is that it can be completely removed from a home. Mold particles are everywhere and can travel place to place through clothes, vents, and other means. These are not generally harmful; it is when a colony begins to develop that the real trouble occurs. Learn 7 ways in which mold manifests itself.



Mold’s purpose is to break down decaying material in nature to promote new life. No one knows how many species there are; it is estimated that tens of thousands of types exist. Still, experts have given at least two types of classifications to mold:

Hazard Classes A, B, and C: In laboratories, mold can be classified from Hazards A-C, or highly harmful to health seeking immediate attention, to not particularly harmful to health.

Allergenic, Pathogenic, Toxigenic: Allergenic molds induce allergic reactions, such as asthma. Pathogenic molds are especially dangerous to those with illness or compromised immunity, including infants and the elderly. Toxigenic molds, also called toxic molds, produce mycotoxins and so can be as dangerous as to cause death.

7 Common Types

Black mold: Black mold is your most infamous type of toxic mold. Its scientific name is Stachybotrys. It can be dark green, gray, or black, and thrives in dark, warm places with high humidity. Call a mold remediation professional to remove this safely.

White mold: Mold that is white in color may likely be forms of Aspergillus, Penicillium, Mucor, and Cladosporium. These molds can come in many colors and types and range from allergenic to toxic. They may grow on fabrics, upholsteries, carpets, wallpapers, and in ventilation systems.

Pink mold: This common mold painting the edge of your shower curtain pink is called Serratia Marcesence. It feeds off of your soap suds remaining on the area and thrives in especially moist, unventilated spaces. Remove with a part-vinegar part-water solution. If the problem is still there, replace damaged items. Pink mold may also be found on food or compost, in which case it is Fusarium, a far more allergenic and toxic mold that spreads quickly.

Orange mold: Orange mold can be a myriad of mold species and grow in diverse areas. This is a slimy species with animal and plant-like characteristics. This is a pathogenic type, not immediately harmful to a healthy body but injurious to yourself and your home nonetheless.

Yellow mold: If you see yellow mold, call help immediately and do not inhale. Aspergillus typically can be this color.

Green mold: Aspergillus, Penicillium, and Cladosporium are common types, though many others exist. Trichoderma is another mold. It has white and green spots. These produce mycotoxins and dwell in damp ventilation systems and can damage buildings.

Brown mold: Brown mold can be molds transitioning from white to black such as Chaetomium. These seem to be common molds produced due to water damage and need immediate remediation service.
