Are you in love with that picture or do you actually have a plan that will work with that color, such as a home with lots of paneling painted white and little wispy areas to paint that color, and furniture upholstered in colors that will just not work with anything else. Ugh, I fell into the grey trap years ago (about the same color of grey) when I was trying to decide whether to upgrade and refurbish or just buy another house. Realtor took me to the grey house I fell in love with. I decided just to redo my house to be the grey house. I found after painting all the walls in my DR and living room and foyer, that the only thing that looked good in my house in gray was the foyer and with the furniture and upholstery I liked in the LR and DR, that had to go. That grey just did not work with my Chippendale tables or Queen Ann DR set. I had marble foyer and lots of white molding and woodwork stuff in foyer but I still ended up putting grass cloth over the grey of the foyer, DR and LR. Furnishings that went with gray just did not go with my style. So I ended up with greige and cinnamon grasscloth wallcovering and furniture that I loved. I even put a black oriental table in the foyer and never worried about the gray again. My house was now much prettier than the grey house. O, if only the grey house lady could have seen my house, she would have put grasscloth everywhere and begged for my Oriental painting of magnolias, brass chinese hope/faith/charity letters, my satsuma vase and umbrella stand, the pagoda lamp shade on the black oriental table.

Try picking up a quart of plain white and a quart of the Weimaraner color in the finish you want for your trim (sheen can alter color perception), along with some dixie cups, plastic teaspoons, cheap foam brushes and something to sample on. Mix some different dilutions and sample until you like the color, keeping track of how much white and how much gray is in each sample. The paint store should be able to mix dilutions of different percentages, like 10%, 25%, etc. or you can mix them yourself: if a 20% mix works you can mix 1 part color with 4 parts white - 4 quarts is one gallon, so 1 gallon white + 1 quart color. 10% would be 1 part color and 9 parts white (1/2 quart color to 1 gallon + 1/2 quart white). 25% would be 1 part color + 3 parts white. Just make sure to mix up more than you think you need because subsequent mixes may be just the teeniest but off, but that happens with professionally mixed paints too which is why "boxing" paint (mixing multiple gallons together) is often recommended. Sometimes adding just a dab of a color to take the edge off the white can work wonders. Some people use this method for ceilings, too. Worst that happens is you're out $20 and a couple of hours fooling around with paint. :-)

"Why wouldn't the sales person tell me they are not truly white?" They are white, just a white with grayish undertones. Every "white" has some other back tint, gray, yellowish, etc. Technically white is not a color but a shade. You blame the dealer but why didn't you look at the color white and match it against the paint color you wanted to use?

Thank you. I think for the wall I'll go a couple of shades darker than the gray mist.
