Those colours work so well. I especially like the club logo against a black blackground, like in the red and yellow jerseys.
In fact, I hope they go with designs similar to the red and yellow - plenty of black in the NRL with tigers, panthers, warriors.
Almost no red dominant colour jerseys - dragons and rabbitohs part red, dragons away only true red jersey. Great colour should be used more.
Yellow is the same - Broncos away only true yellow jersey.
What other colours is the NRL deficient in? Green?
