Quick answer: To use AI to choose paint colors, take two or three daylight photos of the room, upload them to ChatGPT or Claude, describe the mood you want and the things you are keeping (floor, trim, cabinets, furniture), and ask for three specific Sherwin-Williams or Benjamin Moore colors with the reason for each. Use Perplexity to research the finalists, because it answers with links to its sources. Then paint large samples on the actual wall before you buy, since no AI tool can see the real light in your room.
That is the whole method. The rest of this guide shows you exactly what to type into each tool, how to photograph the room so the advice is useful, and where AI color advice tends to go wrong. We are a painting company in Easton, PA, and we see homeowners bring AI color ideas to estimates all the time. The good ones all followed roughly this process.
What AI can and cannot do with paint colors
Chat assistants are good at the thinking part of choosing a color: narrowing a direction, explaining undertones, suggesting trim and ceiling pairings, and reacting to the things you already own. They are weak at the seeing part. A phone photo shifts color with the camera's white balance, and every screen shows color a little differently. So treat AI as a smart, patient color consultant who has only seen a picture of your room, never the room itself.
- Good at: shortlisting colors that match a mood, explaining warm versus cool undertones, flagging clashes with a floor or countertop, suggesting sheen by room, and building a whole-house palette.
- Not good at: judging the exact shade in your light, confirming that a color name and number really match, and predicting how a color looks at full wall scale.
Step 1: Photograph the room the right way
The quality of the advice depends on the photos. Before you open any AI tool:
- Shoot in daylight with the blinds open and the lights off, then take one more photo in the evening with your normal lamps on.
- Stand in a corner so the photo shows two walls, the floor and the ceiling line.
- Include anything you are not changing: flooring, trim, cabinets, countertops, tile, a fireplace surround, large furniture.
- Note which way the main window faces. North light reads cooler, south light warmer, and AI cannot tell this from a photo unless you say so.
- If you already have a current wall color, write down its name and number so the tool has a reference point.
How to use ChatGPT to choose paint colors
ChatGPT accepts photo uploads in the same chat window where you type. Attach your room photos, then paste a prompt like this and fill in the brackets:
Here are photos of my [living room]. The main window faces [north]. The floor is [honey oak], the trim is [white], and we are keeping the [gray sofa and brick fireplace]. I want the room to feel [warm and relaxed, not yellow]. Recommend 3 Sherwin-Williams or Benjamin Moore wall colors. For each one, give the color name and number, its undertone, why it works with my floor and trim, and the sheen you would use.
Then push the conversation forward with follow-ups. These are the ones that tend to produce the most useful answers:
Which of the three is most likely to look different at night under warm bulbs, and why?
Should my trim stay the current white, or is there a white that works better with your top pick?
I have an open floor plan. Suggest a color for the adjoining kitchen that flows with your top pick.
ChatGPT can also create an image of a room in a suggested color. That can help you see a direction, but the generated image is an illustration, not an accurate color match, so do not order paint from it.
How to use Claude to choose paint colors
Claude, made by Anthropic, also lets you upload photos and ask about them. It is a good place to describe the feeling you want in plain language and to ask for an honest check on a color you are already leaning toward. Try a prompt like this:
I am attaching photos of my dining room. The table is dark walnut, the chairs are cream, and there is a brass light fixture. We want the room to feel intimate and grown-up for dinner parties, not dark or heavy. I am leaning toward [Benjamin Moore Hale Navy]. Tell me honestly whether it will work with these finishes, what could go wrong, and give me two alternatives with names, numbers and undertones.
Claude is also useful for whole-house planning. Paste a list of rooms with their light direction and fixed finishes, and ask it to build a palette of three to five colors that connect from room to room, plus one ceiling white and one trim white for the whole house.
Here is my house, room by room: [entry, north light, slate tile], [kitchen, south light, white shaker cabinets and butcher block], [family room, west light, oak floor]. Build a connected palette from Sherwin-Williams with one main neutral, one accent and one trim white. Explain which rooms get which color.
How to use Perplexity to research paint colors
Perplexity works differently. It searches the web and shows numbered sources with its answer, so it is best for research, not for judging your photo. Use it once you have two or three finalists:
What is the LRV and undertone of Sherwin-Williams Agreeable Gray (SW 7029) and Benjamin Moore Revere Pewter (HC-172)? How do they compare in a north-facing room? Cite manufacturer pages where possible.
What do designers say about painting a small bathroom with no window a dark color? Include sources.
Click through the citations. Perplexity is only as reliable as the pages it finds, and the manufacturer's own color page is the source to trust for the official name, number and LRV.
A 15-minute AI color session, start to finish
- Take three daylight photos and one evening photo of the room.
- Upload them to ChatGPT or Claude with the prompt above and get three suggestions.
- Ask the follow-ups: night lighting, trim white, ceiling, sheen.
- Run the same photos and prompt in the other assistant. Where both agree, you have a strong direction.
- Take the two finalists to Perplexity to confirm LRV and undertone with sources.
- Look the finalists up on the brand's own website and in a visualizer tool to confirm the names and numbers are real.
- Order large samples of the top two and test them on the wall.
Where AI color advice goes wrong
Screens are not real light
Your photo and your screen both change the color. Cameras adjust white balance automatically, phones and laptops display color differently, and a color can also shift between daylight and warm bulbs. This is why a gray that looks perfect in a chat can read green, purple or blue on your actual wall.
Color names and numbers can be wrong
AI assistants sometimes pair a real color name with the wrong number, or describe a color that does not exist. Always confirm every suggestion on the Sherwin-Williams or Benjamin Moore website before you buy. Hex codes an AI gives you are approximations too, so do not ask a store to mix paint from a hex code.
Small chips and screens hide what full walls show
Color intensifies across a whole wall. A soft color on a chip can feel much stronger on four walls. Test with large samples: paint two coats on a poster board or use peel-and-stick samples, which both major brands sell, and move them around the room. Check them in the morning, afternoon and at night before you decide. Light Reflectance Value (LRV) helps here too. It runs from 0 for black to 100 for pure white, so a low-LRV color will make a dim room feel darker.
Free brand tools to use alongside AI
- Sherwin-Williams ColorSnap Visualizer lets you try Sherwin-Williams colors on a sample room or your own photo.
- Benjamin Moore paint colors lists every color with its number and LRV, which makes it the place to verify an AI suggestion.
- Adobe Color can pull a palette out of an inspiration photo, which you can then ask ChatGPT or Claude to match to real paint colors.

When to call a painter
AI is a great way to arrive at an estimate with a clear direction. It is worth bringing in a professional when:
- Two samples look close on the wall and you cannot decide.
- The room has tricky light, such as a north-facing room, a dark hallway or an open floor plan where colors meet.
- You are going from a dark color to a light one, or the reverse, which can change how many coats and what primer the job needs.
- It is an exterior, where brick, roofing and stone also have to work with the paint.
Every Joseph Assise III Painting estimate includes a free color consultation. We look at your actual light, apply 12x12 inch or larger test patches of your top choices on your walls, and give you a written color plan before any work starts. Bring your AI screenshots and notes. They give us a fast, clear picture of what you like. See how our color consultation works or book a free estimate anywhere in Easton and the Lehigh Valley.
