Well at the moment every color of lens is defined as a "collection", that said in this case I can see prizm lenses on several frame colors, maybe they want to underline the properties of this lens
It's interesting, most of this HR collection has the pretty boring matte black and Prizm Grey lenses combo. However, the Gascan now has another HR frame that is matte black but the dots are green and the lens is Prizm Jade Polarized with a bright yellow O icon (would really go well with Oregon Ducks gear) as opposed to the original steel with grey.
Also, the regular and AF Frogskins have a High Res Polished Sapphire frame with Prizm Black lenses and the Holbrook has a snazzy matte black frame with blue dots and Prizm Sapphire lenses. So they switched up the original boring combos with some cool frames and lenses.
