I kind of like the blue.

Yes, if I stuck with the blueskin, that would certainly be the simplest approach.

I realized I forgot to say what material will be used on the painted part of the house. It's Boral, vertical panel, nickel-gap. This:

Lighting impacts every color, so the stone will look a bit different on each surface as well, as will the paint color you choose. This is why you have to test your colors on all 4 sides of a house and look at them at different times of the day to be certain you have the right color and there are no surprises.

What color is the grout going to be?

The good thing about lighting changes is that it impacts everything equally, it doesn't just make one of the colors on one side of a house more yellow or more blue, it will add the same color to each surface.

Get a piece of the roofing material, set it next to the stone, then pick paint colors that coordinate well with both. I often like to match the siding color to the grout color..

@Jennifer Hogan, yes, I've been looking at colors with a roof sample and the stone (although I can't easily move the stone to see it on different sides of the building, since it's only installed on one side right now). The plan was to use a completely different color for the 2-story wing, and we were focused on relatively dark colors, but I'm having a hard time figuring out what will feel separate, while not competing too much with the stone or with the landscape.

Also, there won't be any grout showing. The photo of the stone above is a completed interior wall made of the same stone (natural stone found on the site).

I would use a really gray blue.

First, i would do the body of all painted surfaces the same color on both wings. It will look more cohesive and connected. I would get a couple darker samples to try since the stone and the roof need a coordinating tone. Try SW Peppercorn. It would ground the home and pull everything together. (Minus the blue of course.

I think Beverly’s suggestion is spot-on. Our house was painted in Sherwin Williams Peppercorn when we bought it four years ago. It is a warm enough gray to play well with warm colored stone, pavers, and outdoor furniture (warm red). And our roof at the time was weathered wood, which it went well with. It does look like a blue-gray in most lighting conditions. (We just went through a major hailstorm and I decided to go with a deeper blue-gray, so we chose Pewter for our roof and Benjamin Moore Baby Seal Black for the body.)

This is Peppercorn from Houzz photos:

I would prefer more contrast between the siding and roof. Peppercorn looks too similar to the roof to me. What about a light cream or lighter grey?

IMO you choose a colr from the stone maybe a pale gray with a undertone of blue.

I love how Peppercorn looks in my opinion it's a good option.

Thanks everyone. I will try a sample of peppercorn. On my screen it looks green/brown rather than blue/gray! I would go for a gray, but DH hates gray and refuses to "live in a gray house." But if there are suggestions for blue-grays, I'll explore them. He's more likely to agree if they're not "just" gray. From what I've seen, lighter colors read too bright outdoors, and the house could easily look like a beacon on a hill, which we don't want.

All of the siding area will be one color, with another color for the fascia trim. There are two places that were supposed to be black metal panels to match the windows, because they are mostly window with only small spots that would be some other material--the "bridge" between the two wings, and the wall that's underneath the very deep cantilevered roof on the end of the building on the left. Those spots will be be the same flat stuff that the fascia are made of (rather than nickle-gap siding). There was some trouble with the metal panels, so we decided to go with dark gray paint and use the same color on the fascia. The BM baby seal black could be a great option for those spots.

So, the two colors we have been considering are SW In the Navy and Naval. Naval has a gray undertone. We had another blue but it was too bright outdoors, so we went darker, because DH is insisting on blue or green or gold, anything but gray. (I also like blue, but I want something that goes, and that I won't look at every day and regret!) I'm not as good at creating these images as you all, but here are a couple of melanges showing those two blues, the stone, and the roof in different lights:

I should add, DH likes this low-key blue, but I haven't been able to figure out what it is. This house has both stone and roof in similar colors to ours:

Looks like it's going to be a great house! FWIW we had 3 houses go navy in our neighborhood this year - 2 are def too bright (in my opinion) and they used paint with some sort of sheen which cheapens the look of the house I think - one is a DARK matte navy and looks terrific - whatever you choose, I would do a large sample to test it out

Fortunately all of the varying appearances of the roof are earthy tones, rather like you might see in a roof covered in "weathered wood" shingles.

So there are many shades of blue, and green that will work. I think that you definitely will want a gray undertone, to one degree or another.

An old tried & true technique is to pull a shade from your stone, but they likely lean a bit too gray for your husband (except for the tannish ones, which I don't think I would like on the whole house.)

I do like the blue you posted. You are likely going to have to stop into several paint stores to find a chip that is similar. Remember that if you find it in any brand, your preferred brand of paint can usually match (or come close enough) to make a sample.

I would favor a soft, grayish green or blue-green.. Sort of sage-ish, but not leaning yellow.

We used Sherwin Williams Granite Peak in our bedroom, it is a great dark blue/gray. It looks more blue in the light than gray.

We cannot assess true color or your lighting conditions on the Internet. So make sure you get samples. I recommend samplize.com. Very good true color samples. Tip: Do NOT paint directly on your siding. It will bleed through and cause you lots of problems. The samplize sheets have peel backing and you can stick to wall to view from all directions. No disposal of excess sample paints either.

Yes absolutely! Screen colors are always different. I have used Samplize before, and I found it worked great for interior paint. For this project, I've been painting big pieces of cardboard, because I find I need to see a larger size. For the exterior, the builder is going to paint 4ft plywood boards so I can look at them from a distance. Good to know about not painting siding.

I really appreciate all of these color ideas. Looks like I could do green/gray or blue/gray shades in medium to dark (and maybe dark navy) definitely in a matte finish. That will give me a number of good options.

A side issue, but the garage door color has been a real source of frustration. Most manufacturers offer the option of using a SW color, but most darker colors are out because they void the warranty on a door with insulation between layers of steel. So then our only option is the standard black, which will have a high sheen, and it's the "wrong" black (doesn't match the windows or any black or gray we'd use for fascia). I wouldn't care about that, but the garage door is big (double) and it's next to the front door. It's a "design element" whether I like it or not. Apparently we can choose any color if we get a door that's insulated but not sandwiched, which I think means the outer layer that's inside the garage is vinyl instead of steel. Still researching that.

So far the closest color I've found to the sort of grayish blue in the house photo I posted above is BM Buckland Blue. (The IRL chip and sample look very different from the color page on my screen.) I might try it, but I'm guessing it will read too bright outdoors.

Are you going to have wood accents outside? If so, maybe a wood-look garage door?

Yes, ginatay124, there will be cedar soffits under all the overhangs. It would be great to find a wood look door that's convincing (but not actual wood or composite--they are outside my budget). On the other hand, the architects want the door to blend in, so I haven't looked into it very much.

Wood paneled garage door would work. Heavy so more heavy duty lift mechanism is important too.

You can apply wood to standard garage door and stain it any color your wish. We have done this on two homes and it looks really good. We are in the south golf Texas area and used cedar for longevity. It looked great. I matched our wood fence with same semi transparent SW stain. Many nice colors you could use.

@Flo Mangan, how do you apply wood to a standard garage door? We looked at wood (cedar) as well as composite doors that are paintable, but they were all at least 15k, and most were over 20k.

You can check out options on YouTube. Very common here. Here’s one post that might help you. https://buildshownetwork.com/contents/wood-garage-door-how-to-clad-your-metal-door-with-wood

Doesn't adding material to the garage door void the warranty?

I realized I didn't post a pic of the garage location in relation to the front door. I think ideal thing would be painting it the same color as the siding on the garage and on the left hand wing. The trailer is in front of the garage door, and the front door is the transparent area where the light is hitting.

Here's a close-up:

You just need to select a garage door that is made for adding the wood. Go to a local building supply and discuss options with them. They have local “sources” and knowledge to help you make decisions. I would definitely keep external colors uniform for both buildings. Otherwise, they will look like “bad add on”.

I know these aren’t modern houses, but just showing you blues with a silver metal roof. Painting large pieces of poster board is an excellent way to see different exterior colors without making a mess of your siding.

Here are some lighter blues that have the name of the color.

Thank you for the pics, @RedRyder!

We were on site with the builder to look at colors this weekend. Moved the big painted panels all around the house and looked at them throughout the day in varied light and from varying distances so we could see what they'd look like close up and from afar. I had picked out a few navy shades and a lighter blue-gray that I knew looked good with the stone. Previously, many of the colors I'd tried were way too bright outdoors, even some of the darker ones. In the end, our preference for a lighter color beat out our preference for a deeper blue. We picked SW slate tile for the siding. https://www.sherwin-williams.com/en-us/color/color-family/neutral-paint-colors/SW7624-slate-tile It looks lighter and has more depth outdoors, and there's just enough blue in it when seen outdoors that it doesn't just look like a flat gray. All of us who were on-site agreed it went well with the roof and the stone, and honestly I'm relieved! My concern with the dark blues was that they'd look nearly black, and I was right about that. I know that's a look that can be really cool on some houses, but it wasn't what we were going for. Also I was worried about noticeable fading since we get a ton of strong sun up there. The other good thing is this solves the garage door problem, since SW slate tile is light enough that the garage door manufacturers offer it as a custom color option on insulated steel doors. So, I'm doubly relieved about that.

Thank you again for all your input and insights!

That SW color is perfect! Not too gray, not too blue. And it should stand up to intensive sunlight. I love a happy ending.

Now you owe us photos when the siding is up!
