Example: "The dichroic glass door"

As a moving object the door is a specially impressive example for the fascinating colour effects achieved by dichroitic glass: a vivid interplay of the complementary colours of the colour range, with coloured shadows, colour overlaps in the through-view and with reflections depending on the lighting conditions in front of the door and behind it. Every movement of the door as well as changes in the angle of view create new colour combinations.

In this case: the black chair produces a blue reflecting colour.
