I know there's a thread about grey colours, I'm on it but please bear with me.
I'm planning to redecorate my littlest bedroom, which is a small north facing room. I'd like to change the cream all over non colour scheme to a very pale grey, white woodwork and a couple of other accent colours. Due to the smallness of the room and the fact it's a child's room, I'd like to be a subtle grey. Bought some testers, but nothing seems right :-/ so, I'm looking for some tips, pointers, advice 
Also, any good websites where I can get some ideas from? I initially thought a John Deere green as an accent colour, was looking for a plain rug but they tend to be moss green or dirty green. I've been looking at Pinterest but most rooms in there are too theme-y, I'm looking for classy ideas which will last some time (he's only 2yo).
Thanks
