you can change colors in the same room, but not on the same wall..for a nice look..so if you want the one long wall to be the sage green, you can also change the colors on the adjoining walls to a darker or lighter color of the same ..or an entirely different color. I have cocoa in my living room, chocolate in the dining room and they are open to each other..the ceiling is a color like nestle quick and it goes through 2 halls, foyer, living room, dining room , kitchen, dinette, family room and laundry room..all the same color.. the kitchen dinette are a sagey green, the halls are shades of browns or creams and the family room is toasted nutmeg.. they are ALL open to each other

"Your post has me a tad confused. You say you have shades in mind but for what? Can you please expand on what you're thinking you'd like to do, then people can make suggestions from there. " I want to use a blue colour for my kitchen and den area. You can see the den area from pictures 5 and 6. The living and dining area are in pictures 1, 2, 3, 4, 5, and 7 and I want to paint those "rooms" green. What I was saying is I know what colours I want to use and am pretty sure of what shades, but I can't figure out where to start one colour and stop it. As you can see in picture six, one of the walls from the den area sort of wraps around to the dining area with a little alcove in between them. So, I'm not sure where I should stop my blue colour as it wraps around because of how that one wall is. So in picture 6 you see the den area and to the right a bit of the kitchen. I had originally wanted to do the kitchen walls in red, but because those walls also flow into the den area without a wall break to separate the rooms, I decided to just keep it all blue in the kitchen/den area. Colours are not the issue. Where to put them juxtaposed to each other, so as to keep the nice flow the house, is the issue. I hope that helped clear up what I was asking :) "OG, what a wonderful space! I can see your dilemma though with where to paint what shade blue or green. I thought I had it figured out only to move to the other side of the room and think, nope that won't work. If the colors are light enough I think I might just paint the ceiling the same as the walls or possibly a shade or two lighter. We have a few color experts on this board, so let's hope one of them see this and chime in." Thank you for the compliment. Yea I want to do something cool to the ceiling in the living/dining area. As you can see in photo one there's some really nice architecture and I'm trying to find a way to accentuate that. I was thinking of maybe doing the little alcove (photos 5-7) and the triangular area of the ceiling in photo one (the part with the fan attached to it) in maybe the same colour, but then thought otherwise. As far as where the blue and green should meet, I had one I idea of having them meet along the seam in the curve in the wall, as seen in photo seven, almost a line done the middle of the alcove. Again, not sure how that would turn out hehe. I have a bunch of crazy ideas floating in my head but as far as them being a reasonable reality I'm not so sure. Thoughts and comments much appreciated. I love the input and hope to see this room make a stunning transition. I need all the help I can get to make sure this room doesn't look like a circus gone wrong.

You do have a lot of blue, but, if you like it, and enjoy the color and have decorated around it, then leave it. Only one who has to like it is you. Its actually a very pretty blue. Not every house has to be gray, or beige, or white, or blue gray, or green gray, or green. If blue makes you happy, then leave it.

Pictures please
