Getting back to the DHL here. I return with the Colorado Rockies who have been purchased by the same owners as the baseball team of the same name. In an effort to cross brand, the hockey club has been given the purple and black colours of the baseball team.
Again, a 3rd jersey may come later. I've added the yellow from the Colorado state flag. Also, I left the logo alone (also from the state flag). The yellow slightly differentiates between the baseball team and the hockey team. Much in the same way the the LA Kings use gold in the Manchester Monarchs' jerseys.
