Both of my bathrooms are green. The master has tan granite-looking countertops and the walls are painted BM Aura in Metropolitan. Very spa-like. My daughter's bathroom is painted BM Quiet Moments. That color is very nice, as well.

You might take a look at BM 234 "Crisp Khaki". I'd grab the strip with that one and the strips on either side. The historical pallette doesn't really work like a conventional pallette where you have strips with 6 colors on them-it's a bit more disjointed. It will be easier to find lighter/darker tones of a given shade in the classic colors pallette because of the way things are laid out.

So.... I am posting swatches but only because I know you guys are smart enough to know that it's a completely worthless endeavor to try to evaluate paint colors on any kind of illuminated device, like a monitor. Since they rely on the very small RGB color space to render colors, they literally are not able to render color like we see it in real life. The swatches are for reference only - everybody knows you have to get in real life chips. Spanish Sand has Delta E difference of 1.4 from Manchester Tan - which means it's a relatively small difference, but you're going to see a difference when comparing. HC-81 MANCHESTER TAN Benjamin Moore Classic Colors OR-W7U SPANISH SAND Behr Color Collection Lentil has a Delta E difference of 1.2 from Softer Tan - again, means you'll be able to tell the difference between the two colors. SW 6141 SOFTER TAN Sherwin Williams Color N270-2U LENTIL Behr Color Collection Those are the closest colors from Behr. Everything else in the Behr collection is a ways off with Delta E differences of 2 or more - which is a lot and not in the ballpark of being a decent match and therefore not really worth mentioning.

Does anyone have a recommendation for a complementary white that goes with Graytint? All these work with Graytint just depends on which one you like best. Chantilly Lace BM OC-065 Ice Mist BM OC-067 Snow White BM OC-066 As far as gloss level, you could do the same as the walls, eggshell, or bump it up one level to satin (or whatever the next bump up in gloss level is called in the brand you want to buy).
