Not sure about albinoes, but Wikipedia lists a few different colors, arguably _substantially_ different:
Under _Apis mellifera_ subsp. _ligustica_ (the Italian honeybee),

* Bright yellow (golden)
* Very pale yellow
Under _Apis melliferacaucasia_ (Caucasian honeybee),
* Dark with brown spots at times
In fact, both photos below are reported as _Apis mellifera_ , here and here respectively. ![enter image description here]( ![enter image description here](
