This coloring page is truly a masterpiece. It features a giant whale, with its gaping maw open wide. Nemo, the brave and courageous clownfish, is swimming within its depths, looking almost lost. An ethereal light is illuminating the scene with ghostly shadows. To bring this image to life, I would use muted oceanic blues and purples with deep navy shades to really bring out the size of the whale. Forcefield-like blues would further emphasize the otherworldly atmosphere and provide contrast to the lighter blues, while coral-esq oranges could bring out the tone of Nemo's scales. A few silvers and whites could create twinkles of the lightbeam and accentuate the shadows within the whale's mouth. It would be absolutely mesmerizing!
