White trim is a classic way to frame gray siding, from pale grays to deep charcoal. This page sums up the gray and white paint pairs that design sources show, how to match a warm or cool gray to the right white, two AI examples with what the AI got right and wrong, and a way to try it 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 house with beige siding, brown window trim, corner boards and shutters, brown gutters — Example 1 (prompt 1 below; the before is an AI-drawn stand-in house, not a real photo). This is our second run: the first came out blue-gray, so we ran it again with the stronger wording shown below, asking for no blue tint. The siding is now a medium charcoal gray, though it still reads slightly cool. The window trim and corner boards are white, and so are the fascia, gutters, downspouts and porch posts, which the prompt did not list. The brown shutters on the upper windows were removed and replaced with wide white casings, which we did not ask for. The front door kept its red-brown color, maybe a touch redder, and its frame turned white. The brick chimney, the mailbox and the lawn stayed.

AI-drawn stand-in of a tan bungalow with brown trim, brown porch columns and beam, a wood front door — Example 2 (prompt 2 below; the before is an AI-drawn stand-in house, not a real photo): the tan siding is now a very dark charcoal with a blue cast, close to navy-black, darker and bluer than a plain charcoal gray. All the trim turned crisp white, including the gable rakes, the fascia, the porch beam, the columns, the window trim and the window box. The wood front door, the porch, the roof, the lawn and the neighboring houses stayed. We ran the request once.

How to use this page

Pick the gray first, then the white. A light gray with white trim reads soft, a charcoal with white trim reads high contrast. The white should suit the gray's undertone.

These are recommendations, not rankings. We did not find data on which gray and white pairs are most used. The pages we read are from design blogs and home improvement sites, and each paint name below is from a page we opened, listed under Sources, with the code shown there; a name without a code had none on the page. For gray body colors with other accents, see gray house exterior ideas and gray siding colors.

Gray and white pairs from the sources

Gray, as named	White trim, as named	Source and notes
Sherwin-Williams Repose Gray	Sherwin-Williams Alabaster	brick&batten (8 colors that go with gray) calls Alabaster a warm, soft white for a pale gray.
Sherwin-Williams Colonnade Gray (SW7641)	Benjamin Moore White Dove (OC-17)	brick&batten (8 colors that go with gray) says the neutral white brings out the gray's warm undertones.
Sherwin-Williams Dovetail (SW 7018)	Bright white	Hunker calls it a medium gray and pairs it with a light blue front door.
Benjamin Moore Boothbay Gray (HC-165)	Crisp white	Hunker calls it a greenish gray with a hint of blue, shown with a wood door.
Benjamin Moore Chelsea Gray (HC-168)	Benjamin Moore Seapearl (OC-19); Sherwin-Williams Shoji White in another article	brick&batten (modern gray schemes) calls Seapearl a subtle off-white. Its 2024 gray list gives Chelsea Gray an LRV of 23 and says it can look dark in shade.
Benjamin Moore Kendall Charcoal	Sherwin-Williams Shoji White (SW7042)	brick&batten (modern gray schemes), with a Benjamin Moore Wasabi (AF-430) front door.
Benjamin Moore Raccoon Fur (2126-20)	Sherwin-Williams Alabaster	brick&batten (modern gray schemes), a dark gray with white trim.
Benjamin Moore Wrought Iron (2124-10)	White (no paint named)	brick&batten (2024 gray list) shows the charcoal rendered with white trim.
Sherwin-Williams Thunder Gray (SW 7645)	Light trim (no paint named)	Hunker calls it a dark, moody gray; light trim gives a classic, higher-contrast look.

Match the white to the gray

This Old House gives three simple rules: clean grays pair with crisp white, richer and warmer grays pair better with creamier whites, and the deeper the wall color, the darker the trim can be. It also says warm grays have green in them and cool grays have blue. brick&batten adds that warm Repose Gray can take a cool white if you want an industrial or contemporary look. For whites to choose from, see white exterior paint colors and exterior trim colors.

Light gray, medium gray or charcoal

Light gray. With white trim the contrast is soft. Hunker describes Repose Gray (SW 7015) as a light, airy gray with more depth than white.
Medium gray. Dovetail, Boothbay Gray and Chelsea Gray sit here in the sources. brick&batten warns Chelsea Gray can read dark in shaded spots.
Charcoal or dark gray. Kendall Charcoal, Raccoon Fur, Wrought Iron and Thunder Gray are all shown with white or light trim in the sources. If you want dark trim instead, compare black house exterior ideas.

When white is not the only answer

This Old House quotes architectural color consultant Bob Buckter, who advises against defaulting to white trim and suggests muted gray-blues, khakis and pale yellows instead. If you are weighing other trim colors, see siding and trim color combinations. For the reverse look, a light house with dark trim, see white house with black trim.

Test the gray in the right light

This Old House says direct sun washes out color, so view samples outdoors in shade or on an overcast day, and suggests buying a quart to test on a section of wall or trim because colors often look different at full scale. Lighter grays suit houses with plenty of sun, it adds, while darker grays on stucco can add depth in shaded areas.

How to try gray siding and white trim

Photograph the front in daylight, straight on, with the trim, the corners and the roofline in the frame.
Upload it in the tool at the top of this page, or open the exterior designer, and describe the gray. Say "no blue tint" if you want a neutral gray.
Name the parts to turn white and list what stays, such as the door, the roof and the yard, as the prompts below do.
Compare, then test samples. AI grays can drift blue, as ours did, so check the real paint in shade.

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. We ran the charcoal example once. The first run of the medium gray example came out blue-gray, so we ran it again with a stronger prompt and show that second run. 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 grays are the model's reading of the words in the prompt, not matches to the paints named above.

Beige to medium gray. Example 1 made the siding medium charcoal and the trim white, but also whitened the gutters and swapped the brown shutters for white casings.
Tan bungalow to charcoal. Example 2 turned all the trim and porch columns white and kept the wood door, but the charcoal came out close to navy-black.

The exact prompts behind the examples

These are the edit prompts, word for word. Prompt 1 is the stronger second version we used after the first run came out blue.

Prompt 1: neutral medium gray siding with white trim and corner boards

Repaint the siding a neutral medium gray with no blue tint, like light charcoal, and repaint the window trim and the corner boards crisp white. Keep the brown front door, the roofline, the lawn, the plants, the sky and the camera angle exactly the same

Prompt 2: dark charcoal siding with white trim and porch columns

Repaint the siding a dark charcoal gray and repaint the trim and the porch columns crisp white. Keep the wood front door, the porch, the windows, the roofline, the lawn, the plants, the sky and the camera angle exactly the same

Frequently asked questions

Does white trim go with a gray house?

It is one of the most common pairings in the pages we read. This Old House says white trim adds crispness and highlights architectural details on a gray house, and brick&batten and Hunker show light, medium and dark grays with white trim. This Old House also quotes color consultant Bob Buckter, who advises against defaulting to white and suggests muted gray-blues, khakis or pale yellows instead.

Should I use a bright white or a creamy white with gray?

This Old House says clean grays pair with crisp white, while richer, warmer grays look better with creamier whites. brick&batten pairs warm Sherwin-Williams Repose Gray with Alabaster, which it calls a warm, soft white, and also suggests a cool white with Repose Gray for an industrial or contemporary look.

What gray paint colors look good with white trim?

The sources name several: Benjamin Moore Chelsea Gray (HC-168) with Seapearl (OC-19), Benjamin Moore Kendall Charcoal with Sherwin-Williams Shoji White (SW7042), Sherwin-Williams Colonnade Gray (SW7641) with Benjamin Moore White Dove (OC-17), Sherwin-Williams Dovetail (SW 7018) with bright white trim, and Benjamin Moore Boothbay Gray (HC-165) with crisp white trim and a wood door. Test samples first.

Does white trim work on a dark gray or charcoal house?

Yes, it shows up in the sources. brick&batten shows Kendall Charcoal siding with Shoji White trim, Benjamin Moore Raccoon Fur (2126-20) with Alabaster trim, and Benjamin Moore Wrought Iron (2124-10) rendered with white trim. Hunker says light trim on Sherwin-Williams Thunder Gray (SW 7645) gives a higher-contrast, classic look.

Why does my gray look blue?

This Old House says cool grays have blue in them and warm grays have green; Hunker notes Boothbay Gray has a hint of blue and Gauntlet Gray (SW 7019) has brown undertones. Light also matters: This Old House says to view samples in shade or on an overcast day. AI renders can drift blue too: our first try at a neutral gray came out blue-gray, and the charcoal example still reads close to navy.

What front door color goes with a gray house and white trim?

The sources show a few: Hunker pairs Dovetail with a light blue door and Boothbay Gray with a wood door, and brick&batten shows Kendall Charcoal and Shoji White with a Benjamin Moore Wasabi (AF-430) green door. In our examples we kept the existing red-brown and wood doors. See our front door colors page for more.

Can I see gray siding and white trim on my own house?

Yes. Upload a photo of your house in the tool at the top of this page, describe the gray (say no blue tint if you want a neutral gray), say which parts become white and list what stays. The picture shows the idea, not an exact paint match, and the AI may whiten parts you did not name, as it did with our gutters and shutters.

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.
