The Powerstroke 77 is in fact available in blue in 14" size ,unlike the Powerstroke 3
The P77 however is even further away from the OEM head (dual ply like the Emperor, plus a center dot and an inlay ring like the P3). It's very muffled. It would be great for lower tunings on that snare, but it won't sound anything like the OEM head.
Long story short, there are no single ply head with a blue color available for a 14" snare. But going with the Emperor won't completely change the snare, it will focus the attack more and reduce the sustain. Personally, I did not like a dual ply on my Acro (I tend to only like them on snares that are at least 6" deep), but it's not like it sounded bad, I just didn't prefer it.
If you must have blue, Emperor Colortone will be closest (dual ply, but no additional muffling)
