Mold can appear in many colors including black, green, white, orange, and even pink. While color alone does not determine how dangerous the mold is, it can offer helpful clues about its type, maturity, and potential health risks.

At Crown Mold Specialists, we inspect and treat mold in homes and apartments across New York City. Here is what the different mold colors might indicate and why you should not ignore them.

Black mold

Some black mold types, such as Stachybotrys chartarum, can release toxins that affect respiratory health and trigger strong allergic reactions. Black mold is often associated with heavy water damage.

Appears slimy or wet
Often found behind walls or under flooring
May cause serious symptoms in children, seniors, or those with weakened immune systems

Green mold

Green mold is common and may be a type of Aspergillus or Penicillium. While not always toxic, it can still cause respiratory irritation and allergy symptoms.

May look fuzzy or powdery
Common in bathrooms, on windowsills, or around sinks
Typically has a strong, musty odor

White mold

White mold is easy to overlook because it resembles dust or efflorescence. It often grows on unfinished wood, drywall, or fabrics and may become darker as it matures.

Found in basements or low-light areas
Usually powdery or soft
Can still produce spores that affect air quality

Orange or pink mold

These colors often appear in damp bathroom areas and are usually caused by bacteria rather than true mold. Still, they can be a sign of excess moisture and poor cleaning practices.

Found on tile grout or shower curtains
Appears slimy or as a film
Less harmful but should still be removed promptly

Why color alone is not enough

Mold color does not confirm whether it is toxic or safe. Some molds of the same species may appear in different shades depending on moisture levels and surfaces. The safest option is to have the area inspected by a certified mold professional.

When to call for help

If mold is spreading, has a strong odor, or is located near HVAC vents or hidden spaces, do not try to clean it yourself. Contact Crown Mold Specialists for safe and thorough inspection and remediation anywhere in NYC.

Final thoughts

Mold color can give you a clue, but the safest approach is to treat any visible mold as a potential health risk. If you are unsure, get it checked.
