The pitch was not green even at the toss there was only a slight tinge of green looking at it from the boundary, so close up it wouldn’t have looked green.
For the first two day’s of the match there was quite a bit of rain so the pitch wouldn’t have got less green
You can see from the photo of Mitchell Claydon bowling Nick Compton that the pitch was not green.
By the way Mitchell Claydon was your best bowler, and Steve Harmison I think I had better not say much about his bowling, he only bowled two overs when he first came onto bowl.
