It's tough to tell the exact shade, but the little bird who let slip the bit about the gray alternate jerseys had said the logo would include a gray lower stripe.

In the NFL Network's "On the Clock" segment, once it shifted to the host, the Seahawks' most logo appeared over Paul Burmeister's shoulder, featuring two darker shades of blue on the stripes behind the bird's head.
