The Sony NEX range is pretty good, small and light - although some claim the colours are a bit too vibrant. I liked the colours for the fact they were more like I remember things, than the way things actually were :)
If you want "true" pictures you may want to head down the Olympus route - there is a good reason they're used for medical photography (i.e. taking pictures of your cells). They're considered to be able to present "true" colours.
If that's what you want :)
