The only recommendation I have is that once you choose the pink colour that you want get one that is only half as bright. It is amazing how pink always looks so much brighter once it is actually on the wall. And if it is on every wall it can be totally unbearable if it is too dark.

Remember that each accent colour adds more expense - so if you are really set on having one green and white and one pink and white then it may work out cheaper that way rather than adding several accent colours to make two pink rooms different IYKWIM.

Have fun.
