IMF projected economic growth

The IMF have just released their outlook for economic growth in 2010-11. It contains masses of information but these two charts caught my interest given that China has now moved into the position of NZ's 2nd biggest trading partner. The US is also in the pink. I wonder if the colour use was intentional? The numbers represent % economic growth. (NZ ranks 26th in the world on GDP per capita in current prices and US dollars).
