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.
Sputum that is streaked with blood may be due to something as benign as irritation of upper-airway passages due to dry, ambient air. It may be a sign of a more serious medical condition, like pneumonia or a blood clot in the lung, especially if accompanied by other symptoms.
