Yes, yellow mucus often signals a cold is ending, as the color change from clear to yellow/green indicates your immune system's white blood cells are actively fighting the virus and being flushed out, but the real sign of recovery is when mucus becomes clear and symptoms improve, though thick yellow/green mucus can persist for days as you recover.
Does yellow mucus mean a cold is healing? 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.
