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.
At birth the lungs are pinkish white in color; in adult life the color is a dark slaty gray, mottled in patches; and as age advances, this mottling assumes a black color. The coloring matter consists of granules of a carbonaceous substance deposited in the areolar tissue near the surface of the organ.
