The white jersey with the gold pants is more traditional, but I think the white jersey with black pants is more fashionable.
If we were in Paris we would probably have to go with fashionable but since it's Hamilton you have to go with tradition.
People like to say "Black & Gold" and the team does this too. It sounds better.
But the uniforms aren't gold, they're yellow. Not lemon yellow, a darker shade with more orange in it. I'm not sure what the Pantone number is. But they aren't gold. Gold is a metal and the uniforms aren't metallic at all. The Blue Bombers have gold in their uniforms, so do the 49ers in the NFL. We don't, though we love to call them gold.
Whatever the label, the Cats have a great colour scheme that has a long, strong association for many fans.
