The Panthers are working with a really cool color scheme, which is why it is such a shame they use so much grey in their helmet design. I am glad these other designs feature the other colors much more prominently. The top right definitely takes advantage of the blue color incorporated in the team's colors. It is bright and flashy, if that is what the team is going for. Otherwise, the bottom right design is fairly strong. It keeps the grey background color, but with the jaguar logo being bigger, there is a lot more color to the design.
The bottom left design proves just how striking baby blue on black can be. It is a very cool design that features the jaguar logo in a very unique way. Only a few lines are needed to create the design from the black.
