Free sign-up with email or Google. You get 1 free render; free renders are watermarked.

A gray house with black trim works from pale gray to charcoal. Below are the gray and black paint pairs we found named on design pages, where the pages suggest putting the black, and two AI examples that show what the model changed. Then try the look on a photo of your house.

Before and after examples

Example images are AI-generated: both the sample houses and their redesigns. Results change from render to render, so treat them as concepts, not exact product matches.

AI-drawn stand-in of a two-story beige vinyl colonial house with white shutters, white window trim — Example 1 (prompt 1 below; the before is an AI-drawn stand-in house, not a real photo): the beige siding became a medium gray with a slightly cool, bluish lean, and the front shutters and the front door turned black. What it got wrong: we asked for black window trim, but the window casings, corner boards, portico posts and eaves all stayed white. On the side windows only the left shutter of each pair went black, and the right one stayed white. The roofline and the lawn stayed. We ran the request once.

The same colonial with medium gray siding, black shutters on the front and a black front door — Example 1 (prompt 1 below; the before is an AI-drawn stand-in house, not a real photo): the beige siding became a medium gray with a slightly cool, bluish lean, and the front shutters and the front door turned black. What it got wrong: we asked for black window trim, but the window casings, corner boards, portico posts and eaves all stayed white. On the side windows only the left shutter of each pair went black, and the right one stayed white. The roofline and the lawn stayed. We ran the request once.

AI-drawn stand-in of a one-story white board-and-batten farmhouse with a dark gray standing-seam metal roof — Example 2 (prompt 2 below; the before is an AI-drawn stand-in house, not a real photo): the white board-and-batten became a light to medium neutral gray, and the window frames, porch posts, porch railing and front door turned black. The first run came out tan, so we ran it again with a stronger prompt, and this is the image from that second run. What it changed that we did not ask for: the fascia, the gable trim, the eaves and the downspouts also went black, and the metal roof was redrawn darker and glossier even though the prompt said to keep it. The plants and the lawn stayed the same.

How to use this page

Pick the gray first, then decide how much black. The pages we read use black in different amounts: only around windows and roof edges, on all the trim, or on doors, shutters and gutters too.

The named pairs are examples, not a ranking. They come from the pages listed under Sources, with the codes shown there. We found no sales data on which grays are most used.

Gray and black paint pairs named by designers

These pairs are from brick&batten's modern gray exterior schemes, a design firm that sells exterior design services. A color with no code here had none shown on that page.

Gray (where it goes)	Black or near-black (where it goes)	Other details on the page
Benjamin Moore Wrought Iron (2124-10), siding	Benjamin Moore Black (HC-190), trim	Wood accents.
Benjamin Moore Amherst Gray, stucco	Sherwin-Williams Caviar (SW 6990), trim; the page calls it almost black	None listed.
Benjamin Moore Cheating Heart (1617), siding, with Sherwin-Williams Gray Area (SW 7052) on the brick	Benjamin Moore Black Beauty, trim, door and accents	Painted brick with siding.

Grays you can start from

This Old House lists these exterior grays, from light to dark, but does not pair them with a named black: Benjamin Moore Edgecomb Gray, Sherwin-Williams Sea Salt, Benjamin Moore Stonington Gray, Sherwin-Williams Cityscape, Backdrop West Coast Ghost, BEHR Classic Silver, Sherwin-Williams Intellectual Gray, Sherwin-Williams Grizzle Gray, Sherwin-Williams Rock Bottom and Sherwin-Williams Fawn Brindle. For darker body colors, brick&batten's black and dark gray list includes Sherwin-Williams Iron Ore (7069), Benjamin Moore Kendall Charcoal (HC-166) and Benjamin Moore Raccoon Fur (2126-20), which it says has a blue undertone and can take black or white window trim. For more grays, see gray siding colors.

Blacks for the trim

brick&batten names Sherwin-Williams Tricorn Black (6258) for trim, downspouts, eaves and gutters on a house with darker siding; Benjamin Moore Black Knight (2136-10), with green undertones; and Sherwin-Williams Black Magic (SW6991), a warm black. A cool gray next to a warm black, or the other way round, can look off, so put the samples side by side. For more trim choices, see exterior trim colors and exterior colors with black windows.

Where to put the black

Only around windows and roof edges. Ideal House suggests using black trim sparingly in these places, or as an outline for details.
On all the trim, doors and the roof. Today's Homeowner describes charcoal houses where black outlines the trim, windows, doors and roof.
On shutters with stone. Homenish shows stone veneer with black shutters on a gray house. See shutter colors.
Not on the door. Homenish also suggests a contrasting front door, such as red, yellow or blue, to break up the gray and black. See front door colors.

How to try it on your house

Upload a clear daytime photo of the front of your house in the tool at the top of this page, or use the AI exterior design tool.
Name the gray and each black part, for example "window trim, shutters and front door black".
Say what must stay, such as the roof, the windows, the lawn and the camera angle.
Check every window. Our examples show the model can skip some trim or paint extra parts. Run it again with a clearer prompt if it does.

Two examples, and what the AI changed

The examples were run directly on an image model, not through the tool above, so your results will look different. The live tool may use a different model and settings from the ones we used (we used 4 processing steps), so a render from the tool may look rougher or different. The colors are the model's reading of plain color words, not any named paint.

Beige colonial to medium gray. Example 1 got the siding, the front shutters and the door, but left the window trim white and one side shutter of each pair white.
White farmhouse to light gray. Example 2 needed a second run because the first came out tan. The second got the gray and the black trim, but also painted parts we did not name and darkened the roof. For more on this style, see modern farmhouse exterior and board and batten siding colors.

The exact prompts behind the examples

These are the edit prompts, word for word. Prompt 2 is the stronger prompt from the second farmhouse run.

Prompt 1: medium gray colonial with black trim

Repaint the siding a medium gray and repaint the window trim, the shutters and the front door black. Keep the windows, the roofline, the lawn, the plants, the sky and the camera angle exactly the same

Prompt 2: light gray farmhouse with black trim

Repaint all of the white board-and-batten siding a light neutral gray (no beige, no brown, no wood tone) and repaint the window frames, the porch posts, the porch railing and the front door black. Keep the dark metal porch roof, the roofline, the lawn, the plants, the sky and the camera angle exactly the same

Frequently asked questions

Does black trim go with a gray house?

The pages we read say it can. This Old House says black window frames or trim give a strong contrast against gray. Today's Homeowner describes black outlining trim, windows, doors and roofs on charcoal gray houses, and Ideal House suggests using black as an outline or only around windows and roof edges.

What gray and black paint colors are named for this look?

brick&batten lists Benjamin Moore Wrought Iron (2124-10) siding with Benjamin Moore Black (HC-190) trim, Benjamin Moore Amherst Gray stucco with Sherwin-Williams Caviar (SW 6990) trim, and Benjamin Moore Cheating Heart (1617) siding with Black Beauty trim, door and accents. These are examples from one design firm, not a ranking.

Should the gray be light or dark?

Both appear in the pages we read. Today's Homeowner shows charcoal houses with black trim, and This Old House lists lighter grays such as Benjamin Moore Edgecomb Gray and Sherwin-Williams Sea Salt. A lighter gray makes black trim stand out more, and a dark gray makes it quieter. Try both on your photo.

What keeps a gray and black house from looking flat?

The pages suggest adding warmth or texture. Today's Homeowner names light stone, wood, brick or white to soften it. Ideal House suggests varying the gray shades and adding warm wood. Homenish suggests a colored front door or stone veneer.

Which black should I use for trim?

brick&batten's black and dark gray list includes Sherwin-Williams Tricorn Black (6258) for trim, downspouts, eaves and gutters, Benjamin Moore Black Knight (2136-10), which it says has green undertones, and Sherwin-Williams Black Magic (SW6991), which it calls a warm black. Sample them against your gray, because undertones change how black and gray read together.

Can I see gray siding with black trim on my own house?

Yes. Upload a photo in the tool at the top of this page and name each part you want black. The AI may skip some trim or paint extra parts, as our examples show, so check every window and run it again if needed.

Is this tool free, and do I need an account?

Signing up is free and gives you 1 free render. Free renders carry an AiExterior watermark. You need to sign in with an email code or your Google account before a render starts. If you want more renders or clean images, paid plans are on the pricing page.
