A harsher assessment was offered by one Blair aide: '[Cameron] is turning into an absurd figure, and those pictures are beyond parody' (The Guardian, 22 April).
The exercise, however, was successful in highlighting environmental issues on the political agenda – and green issues are clearly on the slate this election season. Indeed, this flurry of colour – exacerbated by Labour's election broadcast of Cameron as a chameleon – caused confusion in some quarters: 'Green is the new blue – and the new red,' surmised The Observer (23 April); the Greens questioned Cameron's sincerity: 'Too Blue to be Green?' (greenparty.org, 21 April).
Having raised his public profile and the political temperature, Cameron must now add substance to his green ambitions if he is to avoid 'the impression that he is a nice chap without any firm policies' (The Daily Telegraph, 21 April).
