It is colour
Thanks for taking the trouble to process the image. Out of curiosity, I repeated the exercise of staring at the 3 dots on the lady's nose, in your colored version, then raising my eyes to the ceiling and blinking once.
Guess what! The image I saw on the ceiling became a B&W negative, but a very poor quality negative with hardly any detail on the dark face, such as eyes and mouth.
I think we need a neurologist to comment.
