Actually, I like what celery girl has come up with in the post showing both the ikea rug and a blue one. Once you have your table centered under the light, you will not have much room left, and the narrower shelving adds texture without mass. Take a look at the two looks: does it seem to you that the first room appears spacious, and the second is a bit busy? That is because the first photo is monochromatic, and relies on texture and depth of colour for interest - a much better idea for your more intimately sized room.

Please clarify this statement... "I like more war, colors like the beige or light tan to coordinate with each other." Also it is hard to recommend colors without some idea of the space and how the rooms relate to each other. Do you have a floor plan, sketch or pictures that you can post to help us give you ideas? Whole house open concept or 3 separate rooms with doors or clearly defined separations for different colors of paint. Also what color & type of flooring, furniture, cabinets, rugs, art etc... Without any of the above I can say I like the following colors & you might start your paint journey with:

Don't use a clock in a dining area. I think the mirrors are a little bit "churchy" feeling. Use painter's tape on the floor and tape out a "rug" 36-42" larger than your table top. Does it run into the baseboards or the furniture? If so, then you need to rethink things. A beautiful piece of original art no wider than the firebox opening should hang 5" above the mantel and set the tone for the rest of your color way here. Right now, the room feels quite cold and exposed. An accent wall is a pretty good idea with the skylight brightening things a lot.

Since it is all so open, I would paint the same color in the kitchen, dining and living. Maybe the creamy white of your dining chairs would work throughout. If you don't want to paint the kitchen, you could bring that same color into the dining/living. Or you could take another shade from that same color strip/card and bring that into the living/dining. Other improvements: your rugs are too small, and so are your lamps. Your dining light is dated and your art is dissonant and not hung correctly. The coffee table is too large and heavy, and I would match drapes to the wall color once you figure that out. I do like your red cabinet and blue cache-pot! Have you thought about installing drown molding? How high are your walls? Here's a creamy white on walls (Navajo White) and brighter on trim (White Dove) so you can get the idea, even though this is not the style of your home.
