FWIW,I've been hanging wallpaper for more than 30 years. Most of the hundreds of rooms I've done, have had latex paint. I have never encountered any problem that I would have connected to the latex paint. Actually the only time I've ever had a problem with the paint under the paper, was in one house. I thoroughly sealed the walls of three rooms in that house before I papered. A few months later, the paper started popping off of the walls, taking the sealer and original paint with it. I have never seen anything like it. After considerable research, I concluded that the original coat of paint was probably applied to new walls while they were covered with dust. This would not be surprising since most builders spray on the original paint. I suppose it's possible the paint itself was defective or so cheap as to be useless. I'd love to hear more about the article that claims latex can cause a problem. I've never heard that before.

I've used F&B in two houses now and basically only use that brand. It is not easy to work with because of the color shift and the undertones. The thing with F&B is the number of pigments used in the paint -- anywhere from 6 to 16 in some colors. It's also factory mixed. The other paints generally use 4 pigments and are mixed in stores. Also, F&B is a clay based paint with an exceptional surface quality in both the flat (estate) and eggshell finishes -- when we went to sell our apartment there were continual comments about the paint, how beautiful etc. It's essential to have the fan deck as the colors on the accordion card are not accurate. That saves a lot on sample pots. Anyone using sample pots should be sure to paint big, big swatches and take care not to put the colors side by side as they will shift and the eye will mix them. For me, rather than try to color match, just go with Ben Moore another of the better brands. They have way more colors, no shift and are easy to work with. They are more accessible and 1/3 the price. Pointing is an excellent all purpose white with a red undertone. It's not the slightest bit yellow. I have it on most woodwork in my house and used it on our our ceilings in our apartment with White Tie on the molding, doors & trim. White Tie is a true ivory with a slight red undertone -- as I found out when I used it on the picture molding in our bedroom that was painted in Skylight, a soft blue. At times during the day it looked pinkish. Pirula is absolutely correct when she says this paint will look different depending on latitude. The colors are formulated in England. They will look very different (and washed out) in stronger light in So Cal or Texas. It was very smart to use the darker primer in California for Teresa's Green, which can be minty in some light, and which otherwise might have looked washed out. Perhaps the OP has solved the whole house color scheme she was trying to do. In general it works best if you stick with one color for all the ceilings, one for all doors, moldings and other woodwork and keep the same color value (lightness or darkness) from room to room. But it also depends on the style of the house.

I get what you're saying about needing some oomph on the walls in your breakfast area. I would prime over the copper brown with white to give yourself a clean slate to begin with. Any white-ish colour is going to get lost when you have such a dominant colour that a) you're used to and b) drowns out any sample board you put up. Speaking of BM, I saw a LR on Remodelista about a year ago that had walls in Overcast and trim in White Chocolate. I'm not sure how it'll play with your floors but I think it's a sensational combination for your wainscoting and walls. It has a presence while still light and ethereal. Is the strip of wall above your cabs the only painted surface in your kitchen?

I don't know Sherwin Williams paint colors so I cannot say how any one would match to F&B. F&B All White is their brightest, whitest white without undertones if I recall correctly. What I do know is that most paint lines have an equivalent -- the brightest white. I would look at those from SW and from BM and others. A lot of the way any white will look depends on location. The same white paint will look much different in Texas, where the light is very strong and New England where it may look more gray due to the light. Noon has the brightest daylight. I would suggest looking at paint samples then. Also in the a.m. and late afternoon. See which looks best to you at all times of the day.
