Q&A

Could there be a material that inverts the colours seen through it?

+0
−0

I had a vision of a creature that touched things, and wherever it touched, it left a mark opposite to the original colour.

For example when it walked across the grass the grass had red footprints, when it touched the wet stone it shone with a patch of white.

Could such a material, a liquid or perhaps a dust, that achieves the described effect exist?

If yes, how might it work or what would it be made of?
