To make a coloring page, one has to prepare materials, which can be colored and easily manipulated using different coloring tools. This is a list of material you may require:

1. Paper: choose a bright, good quality paper which does not bleed when coloring is done on it. The drawing or sketch paper which is most used should be heavyweight.
2. Printer or Drawing Tools: You need a computer, graphic design software and printer in case you decide to produce your coloring page on the computer. In case you are doing it manually take pencils, markers or any other means you would like to use to draw.
3. Ink or Outlining Pen: To produce a sharply distinct style in the defining of the coloring page, an ink pen whose line width is the same throughout the page should be used. It may be a drawing pen or some fine-tipped marker.
4. Eraser: A good erasing material is a necessity to correct wrong or have clear details.
5. Reference Image: In case you are trying to draw something specific, it helps in coloring it with a reference image to tell what to color.
6. Color Palette: Select a color palette that can be appropriate to the subject of your coloring page. This may be a collection of complementary colors or combination of different colors that form a pleasant overall appearance.
7. Place to work: Get a good, bright place to work where you can color, without any distractions around.
8. Protective Cover: When coloring you are on a surface which could be sensitive to coloring materials (e.g. a table), apply a protective cover to avoid any possible damage.
9. Optional Fixative: To permanently seal your coloring page and avoid smudging you may apply a spray fixative. It is more so with works in pastels or charcoal.
10. Coloring Tools:
    • Colored Pencils: These are excellent when the coloring needs to be precise and in detail.
      
    • Markers: They are colorful, and they work on larger areas.
      
    • Crayons: A better option during or on greater strokes and a more texturized finish.
      
    • Watercolor paper/Pencils or Paints: Do not want the watercolor effect? Apply watercolor pencils or watercolor paints to watercolor paper.

Use or modify these resources in any way you see fit, depending on how you wish to make a coloring page.
