This coloring page presents a large octopus swimming in its tranquil underwater world. The octopus has a large bulbous head and long, undulating tentacles in a light blue color. Its body is a deeper shade of blue, merging into the background of blue-green coral and rocks. Small fish swim around it, adding a delightful burst of color to the scene. To bring the image to life, one could use a variety of blues, turquoise and teal to create an underwater oasis. Combined with the bright hues of some of the coral and the splashes of color from the fish, this picture could be filled with life and energy.
