LOL! Glad someone appreciated that bad joke.
Love your profile name by the way.
The most likely case is that your buff probably has Dominant White(I). DW primarily affects black pigment while having no effect or minor on gold series pigments(which includes buff, red).
It is not that easy to make a solid evenly buff bird, stubborn black vestiges on tail or little tiny black flecks on the wings and throughout the body can be a pain to get rid of.. some breeders add DW to Buffs to get rid of the black, and it does the job very well if the buff has only minor (black)flecking.. it can make the buff look cleaner and "light".
I don't know what base most buffs are based on.. it seems a lot are wheaten(eWh) based with columbian(Co) from what few buff discussions I've glanced at. Sorry can't help much there..
The good news, if you want to make more like your bird, try breeding them with wheatens or BBRs, it doesn't matter what sex which parent is which. For example, those two chickens of yours, if bred with wheatens, will produce half "similar to those birds" and the other half won't have Dominant White but what they will be also depends on what base they really were.. if they ARE wheaten then the other half will be regular looking wheatens. The other tricky part is what other genes were used in the Buffs.. like Columbian(good for removing black from the main body). If that's there then a lot of the wheatens will have "not quite right" wheaten patterning.
Wheaten and BBR with DW can look similar at a glance, however differences can be seen at close inspection & technically the term "Red Pyle" belongs to e+ base birds with either DW or occasionally Splash.
