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 generic stand-in of a two-story colonial house with beige horizontal siding, white window trim, a white front door and a medium gray roof — Example 1 (prompt 1 below; the before is an AI-drawn generic stand-in house, not a real photo): the beige siding is now a deep navy on every wall. The white window trim, the white front door and the gray roof stayed in place, so the trim reads as crisp against the dark blue. Run once.

The same house with deep navy blue siding; white window trim, white door and gray roof kept — Example 1 (prompt 1 below; the before is an AI-drawn generic stand-in house, not a real photo): the beige siding is now a deep navy on every wall. The white window trim, the white front door and the gray roof stayed in place, so the trim reads as crisp against the dark blue. Run once.

AI-drawn generic stand-in of a one-story ranch house with white siding, white window trim, a dark gray front door and a charcoal roof — Example 2 (prompt 2 below; the before is an AI-drawn generic stand-in house, not a real photo): the white siding is now a muted slate blue-gray on every wall. The white trim, the dark gray door and the charcoal roof stayed in place. The result is a gray-leaning blue, close to the blue-gray we asked for. Run once.

The same house with muted slate blue-gray siding; white window trim, dark gray door and roof kept — Example 2 (prompt 2 below; the before is an AI-drawn generic stand-in house, not a real photo): the white siding is now a muted slate blue-gray on every wall. The white trim, the dark gray door and the charcoal roof stayed in place. The result is a gray-leaning blue, close to the blue-gray we asked for. Run once.

AI-drawn generic stand-in of a two-story house with light gray siding, white window trim, a red front door and a covered porch with white railings — Example 3 (prompt 3 below; the before is an AI-drawn generic stand-in house, not a real photo): the light gray siding is now a light blue on the walls and the porch back wall. The white trim, the white porch railings and the red front door stayed in place. The blue came out brighter and more saturated than the pale sky blue we asked for. Run once.

The same house with light sky blue siding; white trim, white railings and red door kept — Example 3 (prompt 3 below; the before is an AI-drawn generic stand-in house, not a real photo): the light gray siding is now a light blue on the walls and the porch back wall. The white trim, the white porch railings and the red front door stayed in place. The blue came out brighter and more saturated than the pale sky blue we asked for. Run once.

What the AI can and cannot do

It can repaint the walls of the house in your photo in a blue you name and leave the trim, door and roof as they are, so you can see how a blue looks on your own house.

It cannot match a paint brand's color, show how a blue changes through the day, or say how well it holds up in the sun. As the captions say, the blue can come out brighter than asked. Treat each result as a direction to test with a real paint sample on the wall.

Blue house schemes people suggest

These suggestions come from one published piece: FreshPatio, "25 Blue House Exterior Ideas - Best Color Schemes" by Joe Hats (July 12, 2022). They are design opinions, not rules. We grouped its examples by shade and left out product names.

Blue	What FreshPatio shows with it
Prussian or deep blue	A darker blue with gray undertones, white window trim, a gray slate roof and exposed brick on a large, stately house. The article says Prussian blue needs little upkeep.
Yale blue or classic blue	Blue walls with a red tile roof and bright red front door, or with a red door and red shutters on a modest house.
Cornflower blue	Softer blue siding with a darker blue lower section, a gray roof, a red door, and white fascia, window frames and railings.
Denim blue	Vertical wall panels in denim blue with red fascia, window frames and stair railings, on a large house.
Blue-gray	Blue-gray walls with simple white trim and a gray slate roof, or on an angular modern house with little white trim and a darker blue accent.
Blue as an accent	Cream walls, a brown roof and exposed stone with steel-blue front and garage doors and window planters.
Light blue and white	A pale blue and white exterior under a black roof.
Two-tone gray and blue	A cobalt blue upper story over a muddy gray lower one, or navy-toned roof tiles over gray brickwork, with white detailing.
Cobalt blue	A bold cobalt on a window-heavy house with a gray roof, stone siding and white blinds and frames.
Turquoise	A horizontally paneled turquoise accent wall in a green landscape, or turquoise with a brown brick chimney.
Lilac-blue	A light lilac-blue on a small house with a darker blue door. The article says lilac-blue needs little upkeep.

Tips from the same article:

Match the blue to the house. Choose by home size and style. Bright blues can overpower large houses, so balance them with small red accents.
Tone down bright blues. Use generous white or gray with turquoise and bright blues.
Softer blues blend in. Less saturated, white-tinted blues blend with the sky and with gray, off-white and stone.
Use white to break it up. White detailing breaks up large areas of blue, and gray slate roofs pair well with blue exteriors.
Bold blues need windows. The article says bold blues suit a house with many windows, and that multi-color schemes need planning up front.

Three blues to try on a house

The examples were run directly on an image model, not through the tool above, so your results will look different. In every example the prompt tells the AI to keep the trim and the door.

Navy on beige. Example 1 takes a beige house to a deep navy with white trim, a dark blue with white detailing like the examples in the article.
Slate blue-gray on white. Example 2 takes a white ranch house to a muted slate blue-gray, the kind the article shows with simple white trim and a gray roof.
Light blue on gray. Example 3 takes a gray house to a light blue with a red door. It came out brighter than asked.

How to try blue on your house

Photograph the front in daylight, straight on, from far enough back that the whole house fits in the frame.
Upload it in the tool at the top of this page, or open the exterior designer, and name the blue, for example a deep navy or a muted slate blue-gray.
List what to keep: the trim, door, roof and garage door, as the prompts below do.
Check the whole image. Look at the roof, the trim and the lawn, and run it again if something changed that you did not ask for.

The exact prompts behind the examples

These are the edit prompts used for the three examples, word for word. Change the colors and the list of what stays to suit your house.

Prompt 1: siding to deep navy blue

Change only the wall siding color: repaint the beige siding on every wall a deep navy blue. Keep the white window trim, the white front door, the gray roof, the walkway, the lawn, the sky and the camera angle exactly the same.

Prompt 2: siding to muted slate blue-gray

Change only the wall siding color: repaint the white siding on every wall a muted slate blue-gray. Keep the white window trim, the dark gray front door, the roof, the walkway, the lawn, the sky and the camera angle exactly the same.

Prompt 3: siding to soft pale sky blue

Change only the wall siding color: repaint the light gray siding on every wall a soft pale sky blue. Keep the white window trim, the white porch posts, the red front door, the roof, the lawn, the sky and the camera angle exactly the same.

Before you paint

Test real samples on the wall, in daylight and at different times of day.
Check your HOA or town. Some limit exterior colors.
Plan the trim and accents. See exterior trim colors, front door colors and shutter colors.

Who this is for

Homeowners and buyers who are weighing a blue exterior and want to see it on their own house before buying paint.

Frequently asked questions

What colors go with a blue house exterior?

FreshPatio's examples pair blue walls with white trim, window frames and railings, with red doors and shutters, with gray slate roofs, and with stone or brick. It says white or gray detailing breaks up large areas of blue, and that bright blues can overpower a large house unless balanced with small red accents.

What trim color goes with a navy or dark blue house?

In FreshPatio's examples, darker blues such as Prussian blue are shown with white window trim and gray slate roofs, and denim blue with red trim and fascia. Our first example kept white trim and it stood out sharply against navy. Test a few trim colors next to your siding.

What roof color goes with a blue house?

FreshPatio says gray slate roofs pair well with blue exteriors. Its examples also show red roofs and black roofs on blue and white houses, and a brown roof on a cream house with blue doors. If your roof is not changing, ask the AI to keep it, as in the prompts below.

Is a light blue or a dark blue house better?

It depends on the house. FreshPatio says to choose the blue by the size and style of the home: less saturated, white-tinted blues blend with the sky and with gray, off-white and stone, while bolder blues suit a house with many windows. A preview on your own photo shows which one you prefer.

Can I try blue on my own house photo?

Yes. Upload a photo of the front of your house in the tool at the top of this page, name the blue you want and tell the AI to keep the roof, trim and door as they are, like the prompts below. Check the whole image afterward.

Will the blue come out exactly as I ask?

Not exactly. Our pale sky blue came out brighter and more saturated than asked, while the slate blue-gray was close. Use the render to compare directions, then test real paint samples on your wall, in the light at different times of day.
