Ef asks: How do you aerate your hives? Top and Bottom? If you do it right, the natural currrents of air might flow through and self-cool the black hives. I still wouldn't recommend it though.
Well I use top entrance and bottom entrances and in mid. summer screen top covers and SBB but only when it is real hot 80+ .
But I have nucs that are black with just a bottom entrance just the size of a bee and they do well.
Plus I have DBL. deeps that only had one entrance{bottom} till fall so I don't think any thing is wrong with black hives.
I have mostly black hives and they do well {have not lost a hive since last winter} the only pest I have are VARROA . They build up fast in the spring and made honey {2013 first year I got honey}.
I go buy experience and there's nothing wrong with running black hives in N. pa. I mean that in the nicest way

Plus my hives are in full sun all day long .
