The primary difference is that clear phlegm is normal and healthy, while yellow phlegm suggests your body is fighting an infection.
White or clear phlegm: This is normal. White phlegm with yellowish tint: It could be normal or signal an infection or inflammation. Yellow or dark yellow phlegm: It could mean a viral or bacterial infection or chronic inflammation. Green phlegm: It could mean a viral or bacterial infection or chronic inflammation.
As you get over being sick, your mucus color will likely change from yellow to green. Chances are it will get thicker as well. The change in color and thickness is usually because your mucus now contains debris that's mixed in with the dead white blood cells.
Expert Tip of the Day: Clear Mucus Is a Sign That You're Getting Better.

The mucus starts off as clear, so this is often an early sign you have a cold," Sudhakar said.
Even if you're coughing up yellow or green phlegm, you might not need antibiotics. Your mucus color alone can't tell you if a virus or bacteria is causing your cough. If your cough lasts longer than 3 weeks, it's time to see a healthcare professional.
So, a doctor may use a sputum colour chart to differentiate between viral and bacterial infections and decide whether to prescribe antibiotics. Some evidence suggests yellowish-green mucus might be caused by a bacterial infection , rather than a virus (which won't respond to antibiotics).
In a typical viral respiratory infection, such as the common cold, mucus in the nose starts out as clear but gradually turns yellow or green as the infection progresses. So essentially, yellow mucus just means your immune system has been activated.
To help clear mucus, focus on warm, hydrating fluids like water, herbal teas (ginger, peppermint, thyme), and broths, which thin congestion, while avoiding dehydrating drinks like coffee and alcohol; lemon with honey in warm water is also excellent for soothing and loosening mucus. Hydration is key, as it makes mucus easier to cough up, and certain teas offer anti-inflammatory or decongestant properties, like menthol in peppermint or antioxidants in green tea, to further help.
Although yellow snot can be harmless and usually clears up on its own, there are times when it may signal something more serious — and could require medical treatment. Here are a few symptoms to look out for: Mucus that turns thick, becomes dark yellow or green, and lasts for longer than 10 days.

Five common symptoms of bronchitis are a persistent cough (often producing mucus), chest soreness or tightness, shortness of breath, wheezing, and fatigue, often accompanied by cold-like symptoms such as a runny nose, mild headache, or low-grade fever.
Often viral cases of pneumonia begin as congestion and cough with or without fever in the first few days. When a doctor listens to the lungs and finds breathing sounds are not clear on either side of the chest, a viral cause over bacterial is even more highly suspected.
Call your healthcare professional if your cough — or your child's cough — doesn't go away after a few weeks or if it also involves: Coughing up thick, greenish-yellow phlegm. Wheezing. A fever.
Acute sinusitis symptoms often include: Thick, yellow or greenish mucus from the nose, known as a runny nose, or down the back of the throat, known as postnasal drip.
Cloudy, discolored drainage – like green or yellow – usually means a viral or bacterial infection. If it's bacterial, you could see your doctor for an antibiotic or you might need to just give it some time. If it's a viral infection, antibiotics won't do you any good.
How to Tell If Your Respiratory Infection is Viral or Bacterial. For many of my patients, symptom duration and severity are key indicators. A cold that improves within a week is likely viral, whereas symptoms that persist or worsen may indicate a bacterial infection that requires antibiotics.
Your cough may go away on its own in a few days. But if you've been coughing up phlegm for two weeks or more and your symptoms haven't improved, schedule an appointment with a healthcare provider.
“Normally, mucus is clear. When you have a cold or infection, it might turn green or yellow,” said Alyssa. Clear snot usually signals allergies or some kind of environmental factor that is triggering your nose to start running, such as inhaling dust or allergens. Clear snot is nothing to worry about.

Colds usually begin to wind down during this stage. You may be free and clear at this point. But some symptoms can persist.
Caffeine, Alcohol, and Cigarettes
Alcohol is one of the histamine-producing substances that you should avoid if you feel like you have too much mucus production. Furthermore, alcoholic beverages can cause the membranes within your nose to swell, according to Mayo Clinic.

Stay away from caffeinated drinks and alcoholic drinks, which will actually slightly dehydrate you and make it harder to cough up mucus.
A common misconception is that the colour of your phlegm or mucus indicates if the infection is viral or bacterial. However, having yellow or green phlegm does not mean you are having a bacterial infection and therefore require antibiotics.
The main symptoms of a chest infection can include: a persistent cough. coughing up yellow or green phlegm (thick mucus), or coughing up blood. breathlessness or rapid and shallow breathing.
Some white blood cells contain a green substance (a protein) so if more of these cells are present the greener your phlegm or snot will be. Phlegm therefore comes in a range of colours from white to mustard-yellow to varying shades of green. Coloured phlegm or snot does not mean you need antibiotics.
