Opinions anyone?

Caleb and I have a new bedroom. We decided to play musical bedrooms to give the kids more space to play. Here's the problem. We're sleeping in a bright yellow room with baby quilts hanging over the windows. I obviously need to redecorate. But I can't decide what colors to use. Usually I use blue, brown, and green as my go-to colors. But we painted our WHOLE house blue when we moved in (NEVER do this!), and I am SICK of blue!!! Our kitchen is green and our living room is brown. Caleb is afraid if we paint brown or green, we will overdo a good thing and end up hating it like the blue. We thought about red, but Caleb likes cool, purply reds and I like warm, orangy-reds. I need curtains too. And the room is tiny, so we need something that makes it look bigger... Any great ideas? I love to decorate, but I always fall in love with the most expensive thing there is. And then I'm too cheap to buy it, so I settle for something I secretly think is ugly but is very cheap. So I need something cheap that I like this time. Help!!
