// SwatchLabels.jsx

/*
	This JavaScript is intented to be used with InDesign CS3. Running it creates textframes containing the colo values
	of the the selected rectangles(with applied swatches. You must select at least one rectangle with a color swatch
	applied to it to run the script. The textframes the script creates will be created on a new layer, with created paragraph
	styles applied to them.
