Sure it is. You an see the color line run right into the tail from well into the head end of the bait. You don't have to fill the entire length of the one side with a hand pour to do this, only enough to carry the drops of color you want, then finish with that same pour color. What determines whether the colors will go all the way into the tail is how large the drops of color are. Two inches, 2/3 of the height of one side, will carry five or six different colors, and is all that needed. When the injection is made all of these colors wash thru the column of plastic as it flows in. The color drops with the most volume will flow the furthest and be the most outstanding.
