An AI paint color visualizer repaints a surface in a picture you took of your room or house, so you judge a color next to your own floors, furniture and window light instead of in a sample scene. In Toybox AI, Smart Editor does this job: upload one photo, type the color and what should stay, and download the edited image as a PNG. Sherwin-Williams and Benjamin Moore offer free visualizer apps for their own colors, and multi-brand AI visualizers carry thousands of named colors. Below are instructions for rooms and house exteriors, how the options compare, where screen color falls short, and how to confirm a color with real samples.
What you can do with an AI paint color visualizer
A new color can go on anything already in the photo, from one wall to the whole front of the house. Type each instruction below into Smart Editor's "What should change?" box. Name the color's undertone and finish, then list the surfaces to leave alone, since Smart Editor redraws the entire picture on every edit.
A whole room in a new color
Name the walls, the color with its undertone, and the finish. Mention the ceiling and trim as well, or they may change along with the walls.
Paint all four walls a soft sage green with a gray undertone, in a flat finish. Keep the white ceiling, the white window and door trim, the wood floor, the furniture and the lighting exactly the same.One accent wall
Point to the wall by what sits against it, so the color lands on the right one.
Paint only the wall behind the bed a deep navy blue. Keep the other three walls their current off-white, and keep the headboard, bedding, lamps, artwork and floor the same.Kitchen cabinets
Painted cabinets are hard to undo, so see the color next to your own counters and floor first. Say which cabinets change and list the surfaces around them.
Paint the lower kitchen cabinets a dark forest green and the upper cabinets a warm white. Keep the countertops, backsplash tile, brass handles, appliances, floor and window exactly as they are.Front door, shutters and trim
A paint color visualizer for house exterior projects shows a door or trim color against the siding, roof and brick you actually have. Photograph the house from the street, straight on.
Paint the front door a glossy brick red and the shutters a charcoal gray. Keep the white siding, the roof, the windows, the porch light, the plants and the driveway the same.Siding
Siding is the biggest color on the house, so keep the roof and any stone or brick in the keep list.
Change the siding to a warm greige with white trim. Keep the roof, the stone along the base of the house, the windows, the front door, the landscaping and the sky unchanged.Two colors for the same wall
To compare two colors, make each version from the same starting photo. After the first result, switch "Editing" to "Original photo" and apply the second color. Download both and flip between them on your phone.
A brand's color by name
You can type a paint brand's color name, and the AI approximates it. Smart Editor has no color picker or paint matching, so add a plain description too ("a light warm gray with a beige undertone"). The description is also what you'll check the chip against.
Tips for better paint previews
- Shoot in daylight, straight on. Stand in the doorway or across the room at midday and include the floor and the ceiling line. A photo taken at night under yellow bulbs tints every wall before the edit starts.
- Say what stays, every time. Each edit redraws the image, so a lamp, a switch plate or a picture frame can shift. End each instruction with the surfaces and objects to keep.
- Describe undertone and depth, not just a hue. "Warm white with a cream undertone" and "cool white with a hint of blue" hang side by side on a chip rack and look nothing alike on a wall.
- Change one surface per edit. Do the walls, then the trim, working from the "Latest result". If one change goes wrong, you only redo that step.
- Leave the shape on "Original". Picking Square, Story, Wide or Social makes Smart Editor redraw the whole room in that frame, and the AI may zoom in, add to the edges or rearrange things. "Original" keeps your photo's proportions.
- Upload a real JPG or PNG. Smart Editor takes files up to 10 MB and doesn't accept HEIC. On an iPhone, open Settings, tap Camera, tap Formats and choose Most Compatible, and new photos save as JPEG.
Free paint color visualizer apps and AI editors compared
The paint makers' own apps are free and show exact color names and numbers, because each carries only its own brand. A multi-brand AI visualizer covers several brands at once, and an AI editor takes any color you can describe. As of September 2026:
| Tool | Runs on | Starts from | Colors and surfaces | Cost |
|---|---|---|---|---|
| Sherwin-Williams Color Expert | iPhone (iOS 18 or later) and Android | A photo you take or upload | Sherwin-Williams colors, AI color suggestions, and exterior siding, trim, shutters and doors | Free app, free color chips |
| Benjamin Moore Color Portfolio | iPhone, iPad and Android | A photo, or live video in augmented reality | Benjamin Moore colors, plus a camera tool that finds the nearest Benjamin Moore color to anything you photograph | Free app |
| Housepaint AI | Web browser, plus iPhone, iPad and Android apps | Your own room or house photo | Over 19,800 colors from seven paint brands; detects walls, trim, cabinets and siding on its own | 5 free credits, then credit packs with no subscription |
| Toybox Smart Editor | Any browser | One JPG or PNG up to 10 MB | Any color you describe, approximated by AI, indoors or out | Pro plan, currently 85 credits per HD edit |
| Toybox Room Refresh | Any browser | A photo of an indoor room | A whole-room restyle; name a wall color in "Anything specific?" | Free plan, currently 85 credits for "New look + tips" |
Sherwin-Williams also has a web version of its visualizer, where you pick a sample scene or add your own photo. Housepaint AI's colors come from Sherwin-Williams, Benjamin Moore, Behr, PPG, Farrow & Ball, Valspar and Dunn-Edwards, and it states that it isn't affiliated with those companies.
Which paint color visualizer tool fits depends on how far along you are. Once you've settled on a brand, its own app shows that brand's exact colors and lets you order samples. A multi-brand visualizer suits comparing, say, a Benjamin Moore white against a Behr white on the same wall. An AI editor that takes words fits when you're describing a color you don't have a name for, or changing more than paint in one photo, such as paint plus new curtains.
Limits to know
- Screen color isn't paint color. Sherwin-Williams says actual color may vary from the on-screen version and points you to a physical chip, card or painted sample. Benjamin Moore prints "Screen colors may differ" on its color pages. Use the preview to shorten the list, then decide with a sample.
- Named colors are approximations. A brand color name gets you close to the shade, not a match. Keep the chip next to your phone when you judge the result.
- Details can shift. Smart Editor has no brush or mask, so check outlets, art and window frames after each edit. If something moved, switch back to "Original photo" and add it to the keep list.
- Smart Editor needs a Pro plan. On the Free plan, Room Refresh with "New look + tips" restyles the whole room, and you can name a wall color in "Anything specific?". Expect it to change furniture and decor too, not only paint.
- Label edited listing photos. If a repainted photo goes into a home listing, say right next to the picture that the paint color was changed digitally, and show the original photo too, so buyers aren't surprised at the showing. Check the listing site's own photo rules before you upload. The real estate photo editing guide covers which edits to label.
How to test a paint color before you buy
The on-screen preview gets you to two or three candidates. A sample on the wall makes the final call, and Benjamin Moore's sampling advice gives useful numbers.
- Start with free chips. Sherwin-Williams mails free color chips ordered from its app (in the US and Canada, except Quebec), and Benjamin Moore stores hand out free display chips. Hold each chip up on the wall with a sheet of white paper behind it, so the current wall color doesn't throw it off.
- Brush on a sample. An 8 oz Benjamin Moore sample covers about one 2 x 2 ft area with two coats, and Benjamin Moore says at least two coats give the truest color. Let the second coat dry before you judge it. The samples come in an eggshell finish, so a flat or semi-gloss wall will reflect light a little differently.
- Paint a board, not only the wall. A white foam board lets you move the color to each wall and check it at different times of day. For exterior colors, take the board outside, since Benjamin Moore's liquid samples are interior formulas.
- Try peel-and-stick sheets. Benjamin Moore's Peel & Stick samples measure 9 x 14.75 in, and you can peel one off and stick it up in the next room. Sherwin-Williams sells Peel & Stick samples too.
- Look from morning to evening. Check the sample in daylight and again under your own lamps at night. A bulb's Lighting Facts label rates how warm or cool its light looks, so judge the color under the bulbs you'll actually keep in that room.
- Hold the sample next to the preview. Compare the chip with the edited photo in the same light. If they disagree, trust the sample.
How to change wall color in Smart Editor
- Sign in on a Pro plan or higher and open Smart Editor.
- Add a JPG or PNG (up to 10 MB) of the room or the front of the house under "Your image".
- In "What should change?", name the surface, the color with its undertone, and everything that stays.
- Open "More options", leave "Shape" on "Original", and pick a "Quality": HD (currently 85 credits) or 4K (currently 110).
- Tap "Apply edit". It usually takes about 30 seconds.
- For a second color, switch "Editing" to "Original photo" and type the next color, so both versions start from the same picture.
- Download the PNG and take it to the paint store with your sample. Unsaved results stay available for 24 hours, so save the ones you want to keep.
