About

TestMyPaint repaints a photograph of your room in a colour you choose. It is brand-neutral: we sell the decision, not the paint. We store your photo so you can return to your renders and send it to Google Gemini to generate the repaint. We do not use it to train our own models or for marketing. Photos are scheduled for deletion after 30 days. We may look at uploads and their results to fix problems.

One exception, and it is yours to switch on: a photo you put in a Studio collection is kept for as long as it is in one. Take it out, or delete the collection, and the usual 30 days start again from that moment. Deleting the photo itself removes it immediately, as it always has.

How close is the colour?

Every render is measured. After the model has repainted the walls we sample the painted region, compare it with the colour you asked for in LAB space, and correct the difference — then measure again and show you the result as a ΔE number. Under 5 is a close match; on our validation set of 200 real renders the median after correction is 2.88, against 10.61 for raw model output.

Part of any remaining gap is not an error. A colour chip is measured under standard daylight and your room is not, so a warm-lit room genuinely does make a colour look warmer — and it will do the same to real paint. That is why every result carries the same line: screen colours vary, and you should always confirm with a physical swatch before you buy.

Sample-room photographs

The three rooms you can try without uploading anything are freely licensed photographs from Wikimedia Commons, repainted by the same pipeline your own photo goes through. The repaints are derivative works and are used here under the licences below.

Each room is shown in 5 colours, rendered once in advance. Opening one uses no credits and makes no API call.

Privacy

Usage measurement runs in a cookieless mode that stores nothing on your device and is not linked to your account. Sign-in uses an essential cookie to keep your session active.

We do look at uploads and their results, on a small internal page that lists recent renders, so that a photograph the model handles badly is found by us rather than reported by you. That is the only reason, it is not automated profiling, and it changes nothing about how long anything is kept: uploads and renders are still deleted after 30 days, unless you have put the photo in a Studio collection.

Read the full Privacy notice, including the providers that handle each part of the service and how to request account deletion.
