This coloring page features Dr. Tarakan, an alien doctor from the Monsters vs Aliens movie. He is a tall, green alien with four arms and four eyes. He is wearing a white lab coat and a long, thin, purple tongue. If you want to bring out the details and make the illustration really stand out, you could use a variety of bright and vibrant colors for his skin and eyes. You could use a light purple for his tongue and a White for his lab coat. You could also use blues and greens for his skin, and oranges, pinks, and yellows for his eyes. Black and dark grey can be used to outline the edges and give a nice finishing touch. Have fun and get creative!
