Green's my favourite colour, and it has been since I was a child. It always struck me as a very positive colour, opposite to red. It's a colour that allows things to be set into motion. Then it is also a calm colour, a very natural one. Forests are green. It is the colour of life. It is the colour of environmentalism, of sustainability, of a sense of guardianship of nature. Also, in combination with gold, it forms the national colours of Australia. It's a very youthful, hopeful, and gleeful colour.
