What is a scrolling color changer?

All three of these product families is a version of the scrolling colorchanger invented first by Wybron in 1980. What is a scrolling colorchanger? See the pictures and a quick explanation.

How does it work, you might ask? "Pretty well" is the wiseacre answer to that. It is also a fact. Over three decades, our scrolling changers have been used around the world in widely varying situations. From rental houses to museums, Wybron scrollers have become synonymous with reliability.

Why do I need one, is the next question? Richard Pilbrow says in his book "Stage Lighting Design, The Art, The Craft, The Life", lighting has "four controllable properties: intensity, color, distribution, and movement". Color is second on the list for a very good reason: it is necessary to convey mood and time and place. Additionally, lighting angle (part of Pilbrow's distribution) is critical to making people and objects look natural and real. A fixture with a color changer keeps the angle the same, while allowing variance in the color.
