I can't speak with saltwater locations but for targeting Pinks migrating through the Vedder / Fraser confluence area, my go to fly pattern is a small size 10 nymph hook, hot pink thread wrapped body, few strands of pink crinkle flash and a few strands of holographic flash, topped with a pink bead head. I usually fish strip retrieving on a clear intermediate tip.
Small and sparse is key. A friend and I a few years back were fishing the confluence from a boat in the peak of the pink run and hooked over a hundred between the two of us. We did a lot of experimenting with different flies, sizes and colors. We caught fish on all of them but hookups were noticeably up with with smaller and sparser flies and have done well on them since.
End of the day, Pink salmon aren't overly picky and will bite almost anything presented but thats my go to.
