If an object doesn t have a fill although you can set a contour color the contour will not have a fill. This creates an interesting effect if you have outline width and colors applied to the base object but with no fill and no outline set for the base object to which you want to apply a contour it s an exercise in artistic futility. To set the fill color click the Fill Color selector and choose a color. NOTE Although base objects cannot have a transparency effect in place when you use the Contour tool you can do some interesting things if you first create a contour break it apart CTRL K and then apply the transparency effect to the group of objects that used to be a dynamically editable contour. Try using Uniform transparency at about 90 in Xor mode on a group of 10 to 20 objects. Without a lot of preplanning you can easily generate a color palette simply by experimenting. TIP Creating Special Effects with Contours Because contour intermediate steps travel concentrically from the control object to the end of the effect you can accomplish certain things that would take hours or perhaps not be possible using other tools and effects. For example a blend effect is simply the wrong tool choice when you want interior shading in an object because when you scale an irregularly shaped object such as the letter Q it scales disproportionately. As a result when you blend say a Q to a smaller Q you ve centered inside the larger Q the intermediate blend objects scale different areas disproportionately. Therefore a key to creating smoothly shaded objects is to use a contour effect with many steps and a small Contour Offset value. Here s an example recipe with the Artistic text tool type the letter Q uppercase choose a bold font such as Futura use black as the Fill Color and make it about 200 points in height. .
