Here is what Nike says about the colors. (I was a season ticket holder when the colors changed)
"The new uniform colors are rooted in Seattle’s own environmental hues - the deep blue of the ocean water that tucks into the harbor near downtown and the Seahawks’ stadium. The new color addition called Action Green represents the green of the ubiquitous trees, ferns and moss literally covering the Pacific Northwest landscape. This brighter shade of green is designed to provide a pop of color on the uniform just as the vibrant bright greens pop in the rain-soaked environment"
Ocean blues, Seahawk blue is a dusty med. blue to me and then the navy
Bright green, it's a neon green now.
Bright white for snow capped mountains. (Was silver)
It's mostly a deep blue uniform with a pop of the lime green.
Here is a link to their pantone:
Can't wait to see what you do.
