Gold is not green, or black, or white, so I don't like it.
My main concern, however, is that there is no need for an away shirt. In my lifetime, I have seen Argyle away many more times than at Home Park and anything that departs from Argyle Green on the shirt minimises the impact of the away support. When you look at Ireland or Celtic away there is a sea of green that is so impressive. The same can't be said for Argyle away games, where there are abominations of yellow , gold, purple , orange, or anything else. We call ourselves the Green Army, but too often, when we play away, we are, most certainly, not a green collective. We thereby forfeit the advantage of our unique shirt colour.
