What colors are you looking for? Do you want deeper richer colors? What colors are used in the kitchen and bathroom. You can have unifying elements (trim and floor), but also use accent color to make each room more individual. Your color palette is very neutral. If you want more "pop!" You'll need to think about whether you want warmth: russets, reds, browns, or if you want cool colors: greens, blues, greys, etc. Ralph Loren @ HomeDepot has a lot of accent colors and color schemes that go with them. One other thought. Use an accent wall. Just one. Use your neutral palette to tie things together and give the kitchen some punch by selecting a wall that you'd like to feature.
The feature wall can be a large wall with cabinets and other features that you paint a dramatic darker color, offsetting the color with cabinets and trim. Or small wall where the color is the feature and it pulls out colors used elsewhere in the room. Look in architectural magazines for homes you like the feel of. What is working in them for you? When you figure that out, the whole process will be easier.
If you feel the color palette is too beige, perhaps listen to your own thoughts. Good luck. It is hard to make decisions about color.
PS. I like to do rag roll technique on my walls, to add more color to them. (I often use 4-5 colors, I purchase for $1 in the mis-mixed paints at several stores.) ==== KaCe
