What is the proper way to explain a color pull?

On the basics we line a tube with rods of color.   Then we melt the color into the clear tube and then pull the glass.  This is a line tubing pull.

There is also a color pull dip.   This is where we have molten glass and dip a tube of clear or color in the molten glass and pull.  This can make a special color, or we can layer the color.
