pink puffer cuz the reddish complexion and the pt. hyperventilates .....these pts have less hypoxemia compared to chronic bronchitis ( blue bloaters) ....and so in emphysema u will have no carbon dioxide rentention.
blue bloaters is when pts . will be cyanotic hence blue colour of lip and skin ...cuz its chronic bronchitis and they will have co2 retention and more severe hypoxemia .....
hope i helped !!

Match 2010 is right. Just to add
In Chronic bronchitis there is a lot of ateriovenous anastomosis leading to right to left shunt .As a consequence
There is marked
hypoxemia -------------> Cyanosis Blue) and pulmonory vasoconscrition (Pulmonary vessesl are only vessels in the body which constrict in response to hypoxia)
Pulmonary vasoconstriction ----------> Pulmonary HTN -----------> Corpulmonal (Rt ventricular hypertrophy) ------------> RVF --------------> Generlaized edema (Bloaters)
Hypercapnia due to this marked shunting of blood ----------> warm bounding pulse and papilledema (raised ICP)
But in emphesema there is avleolar septal damage which reduces vascular bed which leads to slight hypoxia (comparatively pink ). In addition there is marked elastic tissue damage ---------> lack radial traction on the brochioles which leads to marked tendency to collapse during expiration because of positive expiratory pleural pressure. So this patient breaths through mouth with gradual release of pressure so that there is more intra bronchial pressure to prevent air way collapse (Purse lip breathing ) .In other words this patient puffs the breathing.
So PINK PUFFER
Best of luck

Thank you..
It's clear now 
So, it's two separated etiologies cause two different diseases but it's likely to be together because of association with the same causing factor (smoking), that's why they're called "COPD" - one disease!
