Color theme for my new room, please help :)?

Too much pink and purple will make the room look childish and a bit sickly. The colours go together (depending what shade of each) however if there is too much of each it can look a bit silly. My room had been purple with bits of pink for as long as I can remember and whenever I come home from Uni I realise how childish it looks. Luckily I've sorted it out a bit by putting up other things. Patterned rugs,blankets and cushions etc, can help the room look less dull. Try not to put too much pink though.
