    I believe that was a slight visibility in the UV spectrum. Like, if the color of undergarments didn’t match the outfit, then it would glow. I don’t know much more about it.

      Honestly, a UV camera/filter for the front camera would be useful for things like applying sunscreen. I’ve contemplated making a smart mirror with that type of functionality.
