Change the Canvas Color
Go to the Properties Editor, World Properties Tab, click in the color bar under Surface:
Background and adjust the color in the color picker circle that displays. You may choose any
color or simply drag the intensity slider down in the color picker as long as you can see the Field
of Influence keeping in mind; the color will Render in an Image or a Frame in an Animation. You
will have to revert to the original white.

Field of Influence
Selecting With Envelope Weights in the Parenting Menu causes Stroke Vertices within the Field
of Influence to be linked to the Bone.
Vertices outside the Field of Influence remain in situ when the Bone is moved (rotated).
Figure 13.19
When Parenting With Automatic Weights and
With Envelope Weights it can be difficult to
achieve an accurate assignment of Vertices when
working with Strokes of irregular shape. A far better
method is to use Parenting With Empty Groups. In
using this method you manually select the Vertices
you wish to assign (link) to a specific Bone in the
Armature.
Construct and position the Armature relative to the
Stroke as previously described.
In Object Mode select the Stroke then press Shift + P Key and select With Empty Groups in
the Parenting menu.
With all Parenting methods Vertex Groups are created for each Bone in the Armature. With the
two previous methods Vertices (Control Points) are automatically assigned to a Vertex Group.
With Empty Groups means the Vertices have to be manually selected and assigned.
