Should Your Interior's Back Page of Each Page to Color have a Solid Color or Shade of Grey?
You don't have to have your back page of a coloring book page a solid color, black or grey, but there may be some color bleed through when the person colors it.
If doing a black and white interior you should put the images to be colored on odd numbered pages and the solid color, blackor grey on even number pages.
This is simple to accomplish, go to the page you want to fill in and click the "Elements" icon and click the "rectangle".
Once on the page, stretch it to fill inside the dotted green line.
Next click on "Fill Color" icon and pick a color.
Once you have done that, you have fill in the back page of a coloring book page.
From there, you can just right click and pick "Clone this page to others" and pick "Select Even" (or "odd" if you are doing it the opposite way than we explained here. OF course you can pick individual pages as well.
