Coloring tips

  • Use shades of deep orange or red for the octopus skin, while choosing bright pinks, yellows, and purples for the various coral types in the background.
  • This illustration is perfect for older children and adults who enjoy intricate details and have the patience for a more complex project.
  • Start by coloring the octopus to make it the focal point, then use a fine-tipped marker to carefully fill in the tiny suckers on its tentacles.
