For the Blues, I went with a design inspired by the current sock striping. Minimized navy a little bit. For the alternate I brought back the roundel (which I always liked). Alternate also features sublimated lines. A nod to their look in the mid to late 90s.
For the Avalanche, the primary is a mix of their classic look and their Stadium Series design. Alternate is a mixture of elements from previous alternates. Also, I tweaked the primary logo a little bit.
