Unless you want to be wedded to tan tones for long, I'd try a more neutral pewter type color. Tan is currently very "in" so a backlash is coming. I'd try to keep it something that can work with either cool or warm colors so it can unify your other rooms. The blue and ivory would seem to do better with a non-tan shade. The stainless steel is also a cool toned element.

If you really love the tan color, then save it for pillows or even wts as they are easier to swap out later.

Do you want to paint the entire space the same color? You can do as many or as few colors as your like as long as they flow. I've posted a link to Maria Kilam's blog where she talks about flow.

Here is a link that might be useful: MK color flow

ac00, We have a similar situation. I just changed out the tan in our foyer to EK Celery, which is a watery pale green. The hallway and dining room are BM Peanut Shell, which looks like caramel. Our Great Room, 2 story is a red, then the kitchen, which can be seen through the open doorways, is Windham Cream. It takes a fair amount of thinking and painting samples on poster board to come up with colors that work and that you are happy with. I tend to like the warmer colors in our living areas and then cooler in the bedrooms.

We had the same issue, as well, when we moved into our new home 6 months ago. I felt pretty overwhelmed by it and although I got so much good advice and help here when I posted a question about it, I just could not visualize the finished product alone.

I ended up hiring a Benjamin Moore color consultant to come to my home to meet with me for an hour....she ended up staying an hour and 20 min and it cost $112...money WELL spent because I really did not know about undertones and which white to use for trim (who knew there were SO many?!) and flow and where to start/stop a color in such an open space, etc

We used one color for our 2 story foyer, the stairway/catwalk area which opens to the back of the house, and the 2 story great room or family room, whatever...we elected to do this because visually when you walk in to the house from the foyer, you can see the stair/catwalk and over into the family room...I am happy with how that turned out.

Our kitchen/morning room is adjacent to family room too, and we painted those one color...

Our dining and living rooms are in the front of the house on either side of the foyer and they are each painted their own color

So we used 4 colors in the big open space but they are complimentary and they flow well from one area to the other...Truthfully, I am still a little bit on the fence about the kitchen/morning room color. Great color although I NEVER would have chosen it myself, works very very well with the finishes in the kitchen, LOVE it in the kitchen itself, but not sure about it in the morning room....maybe too dark, not sure. But its paint and I can change it down the line if I want to.

The biggest thing I learned is that really there are no hard and fast rules. Yes, there are things to consider, lots of things. But if YOU like the color then go for it.

My local SW paint store has a color consultant who will come out for a fee also. If I remember correctly, the salesman in the paint store told me the fee could be applied to any paint I bought in the store. Since you're doing a few rooms, I think bringing in a color consultant or a decorator for an hour's consultation is a good idea. Call around. Maybe some of your local paint stores have this service.
