Light microscope image under normal (left) and ultraviolet (middle) light and an electron microscope image (right) of a partially degraded vermilion particle.

The colour transition from red to black and the white product around the blackened particle indicate that these products are not formed at the same time.

The photo on the right shows how the red intact vermilion particle and the black reaction product differ in structure.
