The False Color view transform is defined in the
filmic_false_color.spi3d and referenced by the OCIO configuration in
config.ocio. In order to add custom 3D lookup tables as new view transforms, they have to be stored in the
.spi3d format and the
config.ocio has to be modified to references these new files.
Update 2020-02-17: The re-write of the tool is complete. It now includes a proper command line interface, it allows to create your own colormaps or to load colormaps from viscm. The release includes lookup tables that should be suitable for people with color vision deficiency. Turbo has been removed from the list of colormaps since it's not useful for people with achromatopsia and it would require to license all code under the Apache license. The matplotlib colormaps are still available.
Update 2020-02-05: The correct mapping of middle grey to the center of the colormap is applied and relative luminance is used for the mapping.
Update 2020-02-04: The lookup tables now have a distinct color for both the low and high clipping range.
I've implemented a lookup table generator that allows you to create your own false color view transforms. Detailed instructions for the installation, colormap creation, arguments for the command line interface and integration into Blender are provided in the README.md.
The first release also includes two false color view transforms, Ignis and Agnoscis, designed for people with color vision deficiency using viscm. Additionally they've been analyzed with Coblis. The generated
.spi3d files and custom
ocio.config can be downloaded here.

ocio.config from the release page.
- Open Blender's directory and navigate to
[2.8x]\datafiles\colormanagement (the 2.8x is a placeholder for your Blender version).

The new view transforms should be available in Render Properties > Color Management > View Transforms after a successful installation.
