blue bloater
A person suffering from advanced COPD with primarily chronic bronchitis rather than emphysema. Blue bloaters are so-named because impaired airflow leads to cyanosis (bluish coloration) and fluid retention (bloating).

pink puffer
A person suffering from advanced COPD with primarily emphysema rather than chronic bronchitis. Pink puffers are so-named because the emphysema drastically increases the effort required to inhale and exhale, causing facial flushing (pinkish coloration) and obviously labored breathing (puffing).
