In pneumonia, sputum is commonly described as what color?

Purulent sputum color reflects the inflammatory response to a bacterial infection. In pneumonia, white blood cells (mostly neutrophils) and bacterial debris fill the airways, giving the mucus a yellow to green hue. This makes yellow/green sputum the most typical description for bacterial pneumonia. Clear sputum suggests non-purulent inflammation or viral infections rather than bacterial pneumonia. Blood-tinged sputum can occur with coughing or minor airway bleeding and isn’t the usual color associated with uncomplicated pneumonia. No sputum occurs with a dry, nonproductive cough, which is not the classic presentation of pneumonia.
