Paint Choices

I've been having thoughts for a little while that I needed to repaint. Last weekend I was trying to clean some dingy looking spots on the wall. They still look dingy. So I guess it must really be time to paint. I got some samples today, and even though I probably won't be able to do it for a little while, I painted some swatches all over my wall. So be warned if you come over. My walls look a little funny.

These photos were taken at night and I need to wait to see how they look during the day etc, but this is what I am thinking. The long wall on the west side all white again. The ceiling white. The long wall on the east, Zinc, which is the darkest grey. The samples that I had of that, were much nicer samples. Some of the others are a little blotchy. Then the south and north walls, wrapping around the kitchen, I am leaning towards the topmost green, called Lemongrass. I was thinking doing my hall in the lemongrass too.

I'm not sure about the purply blue. I might use that on one wall in my bedroom. I'm also trying to decide what to do with the bathroom. I know the ceiling needs to go back to white. But I'm not sure about whether it should be lemongrass or what.

Any thoughts?
