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 tan fiber cement lap siding, white trim, a dark gray roof and a black front door — Example 1 (prompt 1 below; the before is an AI-drawn generic stand-in house, not a real photo): tan siding became a muted slate blue-gray, as asked. The white trim, the dark roof, the black door and the driveway look the same.

The same house with muted slate blue-gray lap siding; the white trim, dark gray roof and black door kept — Example 1 (prompt 1 below; the before is an AI-drawn generic stand-in house, not a real photo): tan siding became a muted slate blue-gray, as asked. The white trim, the dark roof, the black door and the driveway look the same.

AI-drawn generic stand-in of a one-story ranch house with white lap siding, white trim, a brown roof and a wood front door — Example 2 (prompt 2 below; the before is an AI-drawn generic stand-in house, not a real photo): white siding became a warm neutral. We asked for greige, a gray-beige taupe, but the result reads more khaki or olive than gray. The roof, the door and the trim are unchanged.

The same house with warm khaki-tan lap siding; the white trim, brown roof and wood door kept — Example 2 (prompt 2 below; the before is an AI-drawn generic stand-in house, not a real photo): white siding became a warm neutral.

AI-drawn generic stand-in of a two-story house with light gray lap siding, white trim, a brown roof and a green front door — Example 3 (prompt 3 below; the before is an AI-drawn generic stand-in house, not a real photo): light gray siding became a deep evergreen. The roof, the white trim and the green front door look the same, but the green door now stands out less against the green wall.

The same house with deep evergreen lap siding; the white trim, brown roof and green door kept — Example 3 (prompt 3 below; the before is an AI-drawn generic stand-in house, not a real photo): light gray siding became a deep evergreen. The roof, the white trim and the green front door look the same, but the green door now stands out less against the green wall.

What the AI can and cannot do

It can recolor the siding in your photo while usually keeping the shape of the house, so you can compare colors before you order samples.

It cannot match a real ColorPlus color, check what is stocked in your area, or follow every instruction exactly. In our examples the model drew its own version of each color, and one request for warm greige came out more olive. Check the whole image and name what must stay the same.

How to choose a Hardie board color

The points below come from James Hardie (the maker; its press and product pages), Northwest Exteriors (an installer), Brick and Batten (a design blog) and Kylie M Interiors (a design blog). The maker and the installer sell the product. Sources were read on 24 October 2026. Some of them sell siding or lead homeowners to local pros, so treat the color advice as sales-adjacent.

Availability	It varies by ZIP code, profile, texture and local distributor, so ask a dealer before you fall for one color (James Hardie, Northwest Exteriors).

Three Hardie board colors to try

Muted slate blue-gray. Example 1 turns tan siding blue-gray and leaves the white trim, roof and black door alone.
Warm greige. Example 2 turns white siding into a warm neutral. It came out khaki-olive more than gray, so describe the undertone you want.
Deep evergreen. Example 3 turns light gray siding dark green. The green front door stays visible but loses contrast.

The exact prompts behind the examples

These are the edit prompts used for the three examples, word for word. Swap in the color and the list of what stays.

Prompt 1: muted slate blue-gray

Change ONLY the color of the fiber cement lap siding: repaint it a muted slate blue-gray. Keep the white trim, the dark gray roof, the black front door, the driveway and the lawn exactly the same, and keep the camera angle.

Prompt 2: warm greige taupe

Change ONLY the color of the fiber cement lap siding: repaint it a warm greige taupe. Keep the white trim, the brown roof, the wood front door, the driveway and the lawn exactly the same, and keep the camera angle.

Prompt 3: deep evergreen

Before you order siding

Order real samples and look at them outdoors, on every side of the house.
Ask a local dealer which colors, profiles and textures are available in your area.
Decide between ColorPlus and primed boards. Primed means you pick the paint and take on the upkeep.
Check your HOA or town for color rules.
