In the coloring page, Oddish is surrounded by a beautiful natural setting of green grass and bright blue sky. Its dark blue body stands out against the bright colors. The light blue leaves scattered around Oddish's body add a touch of whimsy and playfulness, while its white and yellow details provide an exciting element of contrast. To bring out its dark blue body, we can fill in the coloring page with a deep blue tone. For the light blue leaves, we can use a range of soft blues, from pale to navy. To really bring out the small yellow and white details, we can use a soft yellow and a bright white. The final result will be a vibrant and lively Oddish that is sure to brighten up any coloring session.
