Relight your own room
Take a photo of the space you are lighting. We read the white balance already present in the image, then re-render it under any color temperature you choose — so you can judge 3000K against 4000K in your actual kitchen rather than in a showroom.
Photograph the room you want to light
We detect the white balance already in your photo, then re-render it at whatever color temperature you choose. Works best on a shot with a white or grey surface in frame.

Your photo is processed entirely inside your browser. It is never sent to our server, and EXIF data including location is stripped on load. Nothing is uploaded unless you press “Save & share”.
Getting an accurate result
Include something white or mid-grey in the shot — a wall, a sheet of paper, a mug — then tap it with the calibrate button. Automatic estimation guesses the reference; tapping tells it.
Why your photo already looks neutral
Phone cameras white-balance as they shoot, so a room lit at 2700K often arrives on screen looking almost white. What we detect is the cast left in the file, which is why the calibrate step matters.
What this can and can't show
It faithfully models the color of the illuminant. It cannot model how a lamp's beam falls, how a low-CRI source will mangle specific pigments, or how much light actually reaches the far corner.
