False Color 3D LUTs

Enter the IRE ranges and colors, or choose a preset, and you're ready to go.
Only enter the ranges you want to be colored, the rest of the image will be automatically converted to grayscale.
Adjacent regions should share the same IRE value where they touch each other, e.g. 0-2, 2-4.
The maximum allowed number of rows is 20.

This tool generates 3D LUTs of size 100 to achieve percentage-level accuracy. While this size works in NLEs, it is likely not compatible with cameras or monitors.
You can convert the 3D LUT to a smaller size using the 3D LUT resizer tool, but keep in mind that by doing so, you'll lose accuracy.
