      Some of the holograms I make change colour under pressure, so people can interact with them my touching them. Where I work, we make holograms that change colour if you breathe on them (due to the water vapour in your breath) or if you heat up the hologram to a higher temperature.

      Here’s a link to an image of a hologram changing colour when you breath on it:
