I wonder if Man U, Chelsea or Liverpool Fans spend as much time questioning (or complaining about) their brand colours?
I know most of them only see their teams on TV, so can't really tell the exact pantone, but like it or loathe it, I suspect they are proud that their team is instantly recognisable, as their colours have not changed for generations.
I totally agree with X Isle's view on Puma and the need for consistent use of Green, Black and White - home and away. I just think we have had consistency of the green for a few decades now, so let's just stick with it.
Football fans across the land may not know where Plymouth is, but I bet that we are one of the few sides outside of the premiership with instantly recognisable club colours. So let's not mess about with them.
