I sampled sea salt, quiet moments and rainwashed. In my very brightly lit, wall of southern windows (that have white plantation shutters that REALLY reflect our bright green florida lawn and our equally bright blue skies) open living space the Sea salt turned bright blue, quiet moments gray, and rainwashed bright green. All three of these colors look radically different and more like paint chip in my bright east facing bath that does Not reflect a lot of green and blue into room. i mixed 1/3 of each sample (measured with a scale for exact replicable measurements) and came out with a beautiful soft grayed green blue). Playing with other ratios today with same samples. my local paint store wouldnt take responsibility for calculating formulas based on my mad science projects, so they gave me all three individual formulas for me to calculate what i want. They will mix to those numbers. i am having them do a sample tomorrow with that formula to make sure it comes out good. good luck everyone.

A Sherwin Williams employee told me that he really does not recommend their semi-gloss. The house will be painted in a satin finish, and I wanted the semi-gloss on the trim. Our painters have no problem using the Benjamin Moore paint, and I thought it would be a good product since we are located near the ocean. Thanks for your suggestion. I could have Benjamin Moore color match the most commonly used white that goes with Sea Salt. However, now I am leaning toward BM Super White. Have you used Sea Salt with white in your consulting business? If so, what would you recommend? Thanks for any help.

I'm the OP. Just as an update, not that the info will help anyone else, but I ended up using SW Sea Salt, a 75% formulation, which looks extremely close to SW Sea Salt 100%. I got a sample of it and even though it was a bit bluer than I wanted, it is a very pretty color, and this is one of those situations where I could be happy with something that wasn't precisely what I had originally hoped for, and I am. (Also I was running out of time to make a color decision.) Thank you to all who generously gave such helpful information.
