All the skis will be the same color, but the K2 graphic on the tip will be Pink-ish on the 189's, blue on the 179's, and Red on the 169"s. The Base die cuts will also differ with the same color scheme, but yes they're all lime green skis.
We re-engineered the ski with a progressive sidecut technology that snowboards have been using for a while. Rather than have one radius to tunr on you implement two or more. The result is a ski that can be wider with better tracking (not wanting to hook into a turn on it's own), but retains it's carving capabilities once you pressure the ski to turn and the deeper second radius kicks in.
The lime green is for all sizes (169, 179, 189) and elements on both the base and the topsheet change for each size. The tip logo, helicopter, saftey pin and Seth's shirt on the top will alternate through pink, orange and blue. Same for the base die-cuts.
