You could do it same color different finish - semi gloss for trim

What about ceiling? Does it matter what color the ceiling is?

I paint all my ceilings BM Decorator's White

Even when walls are a different white?

There is white and then there is white.....it looks like this is a great room open concept. What colors exist in your furnishings, window covering, area rugs? I suggest you use these materials as a gauge for white on the walls and then work with a brighter white on the trim in a satin finish.

Scott Design, My furniture is a light beige-almost an offwhite.

I just have off white blinds. Haven't bought the area rug yet.

I think all the same color (different finish on woodwork) is ok, including ceiling.

Another consideration...BM linen white on walls and 50% linen white satin on trim.

What about the kitchen cabinets? Paint or not paint? I vote paint. Then the island can be another painted color.

Avoid ceiling paint that has any hint of blue. It will really show badly against the walls.

The answer to your question is SW Alabaster is a pretty good clean white with some tint of color but not yellow. Very similar to BM Moonlight White, however, for your space I think the Alabaster might be better. Do all the walls and ceiling in a "flat" finish; and the trim in a semi-gloss to set it off just a bit from the walls. All the same color. HOWEVER, you have strong oak/yellow coming off kitchen cabinets, you have oak/yellow coming off flooring and beige-ish furniture all going warm golden tones, so I would stay away from paints with a tint of yellow. It will go really yellow in this situation. There is no substitute for doing 12"x12" sample boards of several colors you think you like and put them in your room and look at them from different angles and different times of day. Believe me, this makes a huge difference. With your ceiling height which I am guessing is around 8' keep the color as neutral as you can because that affects how the tones, bounce around in the room. The lower the ceiling, the less reflective quality within the room. Good luck, hope this helps.

Not painting the cabinets. They're brand new and look amazing in person. Actually a medium brown with a hint of cherrywood and some grayish colors in the wood grain. They look great.

Flo, I've already purchased SW Cashmere paint and I think it's got a little sheen - like an eggshell or something. Would this still be ok?

The "Cashmere" is a "type of paint" SW offers not a color per se. You have to specify what "finish" you want and they have Flat, Satin (low sheen/gloss); Semi-Gloss - higher level of sheen/gloss; gloss highest level of gloss. They have some specialty ones but I don't recommend you go to those. So, you have to select a "color" and I have given you the "flat finish" for your walls, and "semi-gloss finish" for your trim, both baseboard, crown and chair railings. What color is the Cashmere you bought? Cashmere does have a slight sheen, so I'm not sure how that will look in your space. Have you tried painting anything with it? You might just have the "base"? Not sure exactly what is going on here.

BTW, I think Cashmere is one of their more expensive choices and your probably don't need that level of paint for your spaces. So, hope you haven't been taken advantage of here. Obviously, there is confusion. Hope I have unraveled a bit of it for you. Look on the can at the label they print out and stick on the top of can. It should show the "color" SW-XXXX (a number) and the color name along with the formula. See what that says and maybe I can figure out what you have. How much of this did you purchase?

I've got 8 gallons of Cashmere "Low Lustre" in just the base color "extra white."

my understanding was that

1) if I purchased the base I could bring it back when I am ready to pick a color

2) from the description they gave me it sounded like Cashmere doesn't come in the same different sheen levels as normal paint. I bought Low Lustre because part of it will be in my kitchen space.

Also - I bought during a sale so it was just over 30 per gallon

Ok, now I understand, yes you bought just the base color. The low lustre as they call it is more "gloss" than I prefer, but you can try a sample, and see what you think. Probably OK for kitchen. I wouldn't wait too long though. Surely, no more than say a couple months at longest. That explains why you don't have a color yet! I can sleep tonight! lol

Many stores locally will trade back for a different sheen. Ask your store if they'll tradeow luster for matte for the walls. Since more sheen adds to the price, if you have had the paint a long time, you're technically down pricing.

I like matte walls and satin trim.

I agree with oliviag55, but I prefer flat over matte and semi-gloss over trim. Just personal preference. You definitely can "exchange" your Cashmere if you want less sheen, but they will probably only give you in store refund for difference in price and you can't wait long. After all, they have to "restock" it and the sooner you decide the better.

Paint ceiling, walls one color, it expanse the space.

Will matte or flat walls cause an issue in the kitchen when cooking? Since it is an open space - I don't think I want to do low lustre in the kitchen and matte in the living room. Probably best to stick with one finish across both rooms.

Also - I plan to sell the house in 2 - 3 years. Does that make a difference in which finish would be better?

Flat walls would be fine in all spaces. Matte is a little more finicky for my taste. Flat is generally more expected by buyers. More luster tends to point out wall flaws and that is not a good thing. So I would go flat on all walls and ceiling and satin or semi-gloss on trims, baseboards, crown moldings, chair rails, etc. The biggest flat surface that is most noticeable in your photo of your kitchen is the cabinets and backsplash area. It looks like a stone backsplash? Or is that just wall? Then the other wall on the far right is prominent too. I still think all flat finish is the way to go. You could dress up that backsplash with some "reflective" surface such as stainless tiles? But not absolutely necessary. For resale, make it work to the most buyers and that is "neutrals".

Sue - do you have any pictures of the room paint you painted?
