The pictures from Apollo landing despite being in high resolution, does not reveal the right colour of the shoes used by the astronauts during the EVA on the moon. An example - Buzz Aldrin picture from Apollo 11
But a shot from the movie First Man shows in clear detail the colour of the shoes being greenish-bluish.
So, it makes one curious to know whether the depiction of the astronaut's shoes was accurate in the movie. If true, then what is the material that gives this colour?
