bee color

[herbcoop]

I just started this past July and have been feeding my bees and doing hive inspections along the way
Yesterday I did a hive inspection and noticed my caucasian bees that are usually light gold with a little black in them, I had a few between the frames and boxes that had a black torso
They looked healthy and were moving around and none of the other bees seem to mind, so I was wondering if they hatch in this color or if it's normal or maybe some robbers or my bees let these type of bees join them? Like I mention not many of them between the bottom and the medium I have on top of that, I think my eyes caught 20 that were black
"thanks in advance"

Remember that a queen mates with 20± droans so you will have some different color

Thanks for your information, just needed to make sure it's normal
