That concept you found ammofan is sexy. I think any mockup needs more purple and less dark blue.
I think they def should not change the teal/purp at all. Just add a littttttle more orange to pay homage to the Cats. If we change to the Hornets I want the Hornets....I don't want the Horncats. There's no point in changing if we're going to have the same colors.
