No idea about the "4th of July" name, appears to be a tabling species like A. hyancinthus or similar. Similar acro trade names would be red planet, Tierra del fuego, or PC Superman. There's a lot of similar tabling species in the trade, all are uniquely beautiful.
The blue matrix (A. hoeksemai) seems to be a positive ID, and that also does appear to be ORA Purple Plasma (A. horida) or at least very similar to it.
All very nice frags IMO.
