In brief: Older Terms
These are older terms- the pink puffer classically described a patient with emphysema (thin, pink means oxygenated).
The blue bloated means a patient with chronic bronchitis (poorly oxygenated- blue and overweight). We now know there is a lot of overlap between these two types of patients.

In brief: Chronic lung disease
Those terms are sometimes used for patients with COPD or emphysema.
They are usually signs of low oxygen state.

In brief: COPD types
Classically, COPD is separated into patients who predominantly have either chronic bronchitis (blue bloater because they're frequently cyanotic and overweight) or emphysema ( pink and thin or underweight).
Most patients are mixtures of both with 75% or more patients having chronic bronchitis.
