Design a coloring book page that's perfect for kids aged 3 to 4. Create a page filled with large, bold circles, squares, triangles, and rectangles, each outlined clearly for black and white coloring. Ensure that the shapes are easy to distinguish and provide ample space for young children to color within the lines. Style: Black and white for self-coloring Mood: Fun and inviting Make the page inviting and fun for little ones to explore the world of basic shapes and colors through their own creativity.
