Generate me a coloring book with almost 18 to 20 pages, with obviously a very colorful front page, book cover basically. And the pictures or the contents inside the book should be similar to the picture that I sent you. So it should be food, fruits, fast food, sort of something like that. Small pictures, bigger pictures, all of those mixed together. Generate me the coloring book, and you can give me a PDF of 19 to 20 pages.
