Virtual Wall Repainting
Roomagen Repaint Wall is an AI-powered paint color visualization tool that previews specific paint colors on room walls with realistic lighting simulation; any shade can be entered as a hex code. The output shows the room with the selected wall colors applied under the existing lighting conditions. Processing usually takes under a minute using 2 credits per image ($0.23–$0.40 depending on plan), with a free plan offering 6 credits.
A fresh coat of paint is the highest-ROI cosmetic improvement for home sales — a $200-500 paint investment can add $5,000-10,000 in perceived property value. Wall paint color is one of the most impactful yet difficult decisions in home improvement. The biggest challenge is that small paint swatch cards from the store cannot predict how a color will actually look in your room — lighting conditions, room dimensions, existing furniture colors, and adjacent wall interactions all dramatically change color perception. Choosing the wrong color means repainting at another $200-500 plus 1-2 days of additional labor. Research shows 35% of homeowners are dissatisfied with their paint color choice after application. Roomagen lets you digitally test any color on your actual room photo using a hex color picker — see the exact shade in your room's natural lighting conditions before buying a single can of paint.
No credit card required. Results usually in under a minute.

Upload Your Photos
Upload a room photo in JPEG, PNG, or WebP format (up to 50 MB) — any room type and any current wall condition works including painted walls, wallpapered surfaces, faded or stained areas. The AI automatically detects wall areas and separates them at pixel level from ceiling, floor, window and door frames, furniture, and wall-mounted accessories. If multiple walls are visible in the photograph, all wall surfaces are identified. Light sources and shadow zones within the room are analyzed to ensure accurate color rendering across varying illumination.
AI Processing
Select your desired color using the hex color picker for precise shade selection, or draw inspiration from popular paint color palettes. The AI adapts the selected color to the room's actual lighting conditions: walls facing windows appear brighter, corners render darker, and shadow areas show natural color gradation. Differences between matte, satin, and glossy paint finishes are rendered — glossy paint reflects more light creating visible sheen near windows, while matte paint shows even diffuse color across the entire surface.
Download Results
Download your repainted room in under a minute. The output is photorealistic — the color appears natural under the room's lighting, realistic beside furniture and flooring, and consistent with the room's overall color temperature. Create A/B comparisons by reprocessing the same photo with different colors (each version costs 2 credits). Use it as a guide and check a physical sample before you buy paint. Combine with other tools: repaint first, then apply virtual staging or furniture facelift for a complete room transformation.

Common Use Cases
Paint Color Testing Before Buying
Visualize any paint color on your walls before purchasing a single can. Enter a hex code from Benjamin Moore, Sherwin-Williams, or any brand to preview the color in your room’s lighting.
Listing Neutral-Tone Refresh
Digitally repaint bold or dated wall colors to neutral tones for listing photos. Greige, white, and warm beige consistently appeal to the broadest range of buyers.
Bold Color Previews
See how navy, forest green or terracotta would look before committing, and compare it with the existing furniture. Every visible wall takes the color, so for a single feature wall use a photo framed on that wall.
Finish Comparison
Compare how the same color looks in matte, eggshell, satin, and semi-gloss finishes. The AI renders finish-specific light reflection, making it easy to choose the right sheen level.
Accent Wall Color Testing
Test bold colors one run at a time — navy blue, deep green, warm terracotta — and compare how each works with the existing furniture and decor before painting. Every visible wall in the photo takes the color, so frame the photo on the wall you plan to paint.
Rental Property Refresh Planning
Plan quick between-tenant paint refreshes for rental properties. Show the property owner a side-by-side comparison of current wall color versus proposed new color to support rent increase potential with visual evidence. Test whether neutral colors or bold statement colors perform better in the local rental market by generating both options and gathering feedback from prospective tenants or property management professionals.
Unlike small swatch cards that cannot show full-wall appearance under your room's lighting, Roomagen renders paint colors at actual wall scale with realistic lighting interaction. Physical painting costs $200-500 per room in materials and labor plus 1-2 days of work, furniture protection, and drying time — choosing the wrong color means repeating the entire process at the same cost. Paint brand digital simulators (Sherwin-Williams ColorSnap, Benjamin Moore Color Portfolio) use generic stock room images rather than your actual space, limiting the accuracy of color interaction predictions. Physical swatch card tests are free but only 2x3 inches — they cannot show full-wall appearance, and store lighting differs significantly from home lighting, causing color perception shifts. Roomagen processes at 2 credits per image on your own room photograph with hex color picker precision and delivers results in under a minute.

Frequently Asked Questions
Everything you need to know about Roomagen
Yes, by color code: choose a custom color and enter the hex code the brand publishes for the shade — Benjamin Moore, Sherwin-Williams and Farrow & Ball list them. There is no paint-name search, and on-screen color differs from real paint, so check a physical sample before you buy.
The preview renders the color under the photo's own light and in the finish you chose, so it shows more than a small swatch can. Screens and real paint still differ, so use it as a guide and check a physical sample before you buy.
Not reliably. The tool paints every visible wall with the chosen color and has no way to pick a single wall. For an accent-wall preview, use a photo framed on that wall.
It keeps the light that is already in your photo: the color is rendered under the room's own daylight and lamps, and walls facing a window can look lighter than walls facing away. It does not switch the room to other lighting, so check a physical sample in your own light.
No. Repaint Wall changes wall surfaces only; the ceiling, trim, molding, baseboards and door and window frames are kept as they are.
As many as your credits allow: each color is a separate run of 2 credits on the same photo. Download the versions you like and compare them side by side.
Roomagen generates each repainted room in under a minute, making it practical to test dozens of colors quickly. This speed eliminates the guesswork that makes paint selection stressful.
Yes. You can show a room in neutral colors without repainting it. A repainted listing photo is digitally altered, so label it where your MLS requires it and keep the original.
Roomagen preserves wall textures including knockdown, orange peel, and smooth finishes when applying new colors. The paint effect respects the underlying surface characteristics for realistic results.
Use Repaint Wall when you only want to change the wall color and finish; ceilings, trim and floors stay as they are. Use Restyle Surfaces when you want to change wall finishes along with countertops or other hard surfaces in the same image. Use Virtual Renovation when wall changes are part of a larger remodel that includes cabinets, flooring and fixtures. For a brand's shade, enter its hex code and check a physical sample before buying.
