Mucus, commonly known as snot, typically appears clear when you're healthy. However, its color can change significantly depending on your health status.

Mucus Color Changes Indicating Illness

- Yellow or Green: These colors often signal a common cold, viral, or bacterial infection like a sinus infection. The presence of white blood cells fighting infection causes this color change.

- Brown or Rust-Colored: This could be due to old dried blood, indicating a possible injury or irritation in the nasal passages. [Source: Mount Carmel Health]

Important Note: While mucus color can be an indicator, it's not a definitive diagnostic tool. The color alone cannot reliably distinguish between viral and bacterial infections.
