Background
NightHawkInLight's video that inspired this
This paint was initially named SkyPaint. Coolpaint is the name of this project and community from our perspective. We went with Cool Paint because it is exceptionally simple and descriptive of what the paint is.

Results
The current ( April 2024 ) batches have shown about 11 F below ambient temperature at night, or if shaded in daytime ( but still exposed to the sky as much as possible ). That difference is highly dependent on the particular insulated test box of course, it is not a comparable number to other reports that used a different test apparatus.
