Yes, mucus can turn yellow at the end of a cold. This change in color typically indicates that your body is fighting off the infection. The presence of white blood cells, which your system produces to combat the cold virus, gives the mucus a yellow or green tint. While it's a sign your body is responding to the infection, consult a healthcare provider if the mucus color persists or is accompanied by severe symptoms.

FAQs & Answers
