The color of the box helps identify the quality of the Hoya filters in descending order. Basically, the more you pay, the more coatings you have, and better image quality.

The SHMC (99.7%) has the best light transmission of all the Hoyas, so it is superior to both the Pro 1 Digital (97%) and the HD (99.35%)! The list has the worst filter at the beginning of the list, lest the OP mistake what was implied by 'descending order'
