Colors of Mucus (Phlegm, Sputum). Phlegm may be clear (white), yellow/green, brown, grey, black, pink, orange, containing red streaks, or frothy. Phlegm is mucus (sputum) coughed up from the chest. It reveals inflammation in the respiratory organs below the vocal cords (voice box, windpipe, bronchi and lungs). From the color and density of phlegm, and accompanying symptoms, its cause may be suspected.
In cases of infection, the sputum may be green or flecked with blood. If you are unable to produce a sample of sputum, a sample can be induced by your physician or lab technician. You may be asked to inhale sterile saline or a glycerin aerosol, which will help loosen the sputum deep in your lungs.
