Create a coloring book illustration depicting the joyous festival of Diwali. Draw a house adorned with colorful rangoli patterns at the entrance and vibrant diyas (oil lamps) illuminating the surroundings. In the sky, illustrate a bursting firework display with sparkling colors. Show a family celebrating together, dressed in traditional attire, and exchanging gifts. Don't forget to include a beautiful rangoli design in the foreground, filled with intricate patterns and vibrant colors. Encourage children to use bright shades to bring this festive scene to life and make it sparkle with their own creativity.
