I think its a light vs dark issue.
I think a brown jersey, as an alternative to a black jersey, would mean that there would be a bit of a clash playing away to the Warriors, Manly, Broncos and Cowboys to name a few...
Make the home jersey chocolate soldiers and away jersey predominatly white IMO
true, but they seem to have a real reluctance to go back to the brown scheme, I don't know why, it's their heritage and done right, can look really good. Since they've changed their jersey in 1991 from choccy soldiers to licorice all sorts, they don't seem to stick with a colour /design for a real long time and they also seem to want to mimick the Carolina Panthers in the NFL with using black and teal in their color scheme. I'm not saying they are down right commiting plagiarism and Carolina don't own the rights to the colours black and teal but to me, there is a real influence from their colours in the Penrith merch/jersey/scheme.
Would love to know if the Panthers fans would like to go back to Brown and White, because at the end of the day, they are the ones that have to buy the jerseys and wear them around, I'm sure the old school fans would relish it, not so sure about the younger generation though.
