All the colors you are looking at are good colors IMO. I have use Nomadic Desert and Kilim Beige and am pleased with both. I am leaning toward lighter beiges these days but these colors are very easy to work with.

I have SW Macadamia in my living room, foyer, hallways, and at 50% in my master. Love it. Goes with everything.

Does macadamia ever give off a greenish hue? Or is that just my imagination? ;)

A little bit, yes, I'd say, though I'm not good figuring out undertones.

I just painted my living room Nomadic Desert and I really like it. This room is north facing with little natural light. I have seen a little pink once in a while but moving my lamps and changing my bulbs corrected that. I tried Kilm Beige but it looked like the color of a bandaid in my room. I plan on painting my south facing dining room Latte. Good luck with your choices

I've read that beiges will have an undertone of either pink/peach or green. Macadamia probably tends more toward green, but not as much as some beiges.

In the SW fan deck, for the most part the shades on strip numbers lower than the Whole Wheat one tend toward pink/peach (with the Nomadic Desert being the least of those-ND looks like caramel to me). Those strip numbers higher than and including Whole Wheat tend to have the green undertones.

Peachy beiges are tricky. I used Sand Dollar in my foyer which got very little natural light and it looked like a nice, neutral beige. I decided to use it in my kitchen which has large west facing windows, and it looked like refried beans - no lie.

One thought with a basement space is to bring the "outdoors" in by using a creamy yellow (sun), blue (sky) or green (foliage). But the shades of each have to be right.

Muted shades sometimes just look gray in a darker space.

Do you have color corrected light bulbs? That will make a difference as well. Use them now while you are testing out paint samples.

If nomadic desert looked like caramel in my basement I'd be completely sold. But today I went down to the basement & it had a chocolate milky look to it. Macadamia seems like the front runner so far. I'd rather have green undertones than pink. My favorite neutral color in my house is sw relaxed khaki which I have in the MB, but in the basement it looks too green & grey. I want a warmer feel.
Thanks for the advice!

SW Hopsack might be worth a look!!!

Hopsack is a nice color, but I think it will be too dark in my basement.

i have SW Macadamia, in my house, in my private room, in hallway in all over the house except kitchen and bathroom it looks superb, I always have ceramic tiles in my kitchen floor and some type of marbles on wall, it looks brilliant. Tiles in kitchen/bathroom increases the beauty of these two rooms.

Yeah I think I'm really starting to like macadamia. Unless someone recommends another color, I'm probably going w/ it. When i google pics of it, the rooms all look great.
Thanks!
