Ron stands tall and proud in front of a brick wall, a wand firmly in his grip. His ginger hair is a soft contrast to his bright blue jacket, guiding our gaze to his determined expression. To bring out the details of Ron's outfit, use a color palette of cool blues and calming greens. To make the wall more interesting, bring in shades of brown and orange, and maybe even a few swathes of grey to bring out the texture of the brick. As for the wand, a warm gold tone would draw the eye and bring life to the entire image. Finally, Ron's hair is the perfect opportunity to add an explosion of fiery oranges, yellows, and reds. Bringing everything together, you can create a beautiful and vibrant page to color.
