Sonic the Hedgehog stands in the middle of a lush and vibrant green field. He has a purposeful look on his face as he races across the grass. In the background, a clear blue sky dotted with white clouds is visible as far as the eye can see. Sonic's blue shirt and red shoes really make him stand out against the greenery of the field. To color this page, I would use a bright blue for Sonic's shirt, a vivid red for his shoes, and bright greens for the field. Using lighter and darker tones for the clouds and grass could add an extra layer of realism to the scene. Lastly, I would use a warm color for Sonic's face and set the tone with a cool grey shadow.
