Ways to use line colors and weights
 Make a graph paper easier to use by selecting different line weights and colors for each grid division. The screenshots below show the Major Grid with heavier green lines than the Minor Grid's purple lines.
 Set all line weights to fine and pick a different color for each grid division. Get more detailed instructions on this approach in the blog entry "Create Fine Line grid paper for precise plotting". Below shows Major Grid lines set to a darker shade of green than the Minor Grid or Subdivision.
