Antibiotics do nothing against viruses — regardless of whether green mucus is produced. However, the timing of symptoms may offer a clue as to the type of germs present. However, if you start producing excess clear mucus, that may signify allergies due to your body trying to expel dust, pollen and other irritating particles.
If a virus makes its way into your nose and into the air-filled pockets behind your forehead, cheeks and nose — called the sinuses — your nose may start to make extra mucus to clear out the virus. After a few days, it might begin to turn white.
One of the first signs of a cold is green or yellow mucus. The yellow color comes from dead white blood cells, which can turn green if there are a lot of white blood cells and other debris. Whether you keep blowing or rubbing your nose or you fall face-first onto it, blood is the primary reason your mucus can turn red or pink.
It can also stick around your nasal cavity for a while, so lingering blood may just be a light shade of pink. Blood-producing irritation may not be so obvious, however, and it may be a result of something as simple as dryness in the air.
