Magic Sheet Color Scroller Indicator

What does the magic sheet scroller indicator do on Eos magic sheet channel objects?

When the scroller indicator box is checked on a non-button channel object, it presents a visual representation of what color the scroller is in. In v3.2.10 of Eos software and beyond you can enable a text field to be a parameter and select scroller to put the name of the gel color in the channel object.
