Welcome to the LUT Maker
This tool helps you create custom Look-Up Tables (LUTs) for color correction in applications like OBS, based on a photo of a color reference chart.
The process involves these steps:
- Setup the color grid configuration
- Define reference colors for your color chart
- Upload a photo of your color chart
- Process and create the transformation
- Test and adjust the results
- Export the final LUT file
Color Grid Configuration
First, define the layout of your color reference chart:
This configuration defines how your color chart is laid out and how much border to ignore when analyzing each color block.

Save/Load Template
Save locally for this browser, or export a JSON file to move a template between devices.
Reference Colors
Define the RGB values for each color in your reference chart. These are the "correct" colors that your camera should capture.
At minimum, you should include white, gray, and black. Adding other colors will improve the results.
