what is the difference between green and blue pack of hoya lense filters?

The “standard” Hoya filter range comes in the blue box and is multi-coated.

The budget range comes in a green box and cheaper because it is only single coated.

The HMC range has even better multi-coating and, optically, is the rival to the hand-made German filters from B+W or Heliopan.

At the top of the range is the SHMC Pro-1 range.
