If white is part of their colors, then its not an issue for me... the knights probably should have a red alternative (blue shoulders), ive said this many times before, Roosters inagural 1908 jersey is a red jersey with navy and white hoops, not sure why they dont use that, broncos too, they had a yellow inagural '88 jersey, (personally thats my favorite), cowboys a few years back had a silver kit... that is something they shouldve stuck with.
Canberra in white, looks really good, it reminds me of vikings in the snow, or ice giants of norse myths..
