Cloning a color lets you pick up dabs of color from an original (source) image and apply the same color to a clone (destination). Brushes that use stamp-based dab types produce a color based on samples of color from the clone source, which results in an approximation of the original color. Brushes that use rendered dab types sample several colors and load each color onto individual bristles, which allows startlingly realistic results. For more information, see Painting in the clone.
