Coloring Tool in Pencil Software.
The best tool for John to use in coloring his ball in the pencil software is a paintbrush tool. This tool will allow him to use various colors that are available in the software. To do this however, he has to select the outline of the drawing at first, for each part that he wants to use a varied color, and apply the most appropriate color at each place. This he has to do for each part, till his ball is fully colored and to the desired color of his drawing before saving his work.
