the researchers were able to create a “white paint” that doesn’t absorb UV radiation.

Here's the original YouTube video where that image with the ultraviolet caption originated from. In the video the image is clearly from an infrared camera, with a temperature scale on the right side showing the correlation between the false colors and temperature. You can watch the entire video, but I have cued it up to the relevant shot here:

The underlying abstract paper does mention UV reflectance as an advantage of the coating not breaking down after prolonged exposure to sunlight.

But the captioned image is NOT of ultraviolet light. It is of near infrared.

It’s racist paint.
If it were any other color than ‘white’....................

But the captioned image is NOT of ultraviolet light. It is of near infrared.

The captioned image is captured in the Long Wave Infrared (LWIR), 8-12 micron wavelength.
