Cartoon of a man and woman standing in front of a staircase

Create an illustration of two characters in a flat design style, standing in front of a large staircase that has the Brazilian flag painted on it. The characters should be diverse: one is a man with black hair and medium brown skin, and the other is a woman with dark skin and curly hair. Both characters are smiling and appear very happy. Their outfits should incorporate the colors of the Brazilian flag, such as green, yellow, and blue. The man could be wearing a green shirt with blue pants, and the woman could be in a yellow dress with green accents. The background should feature a vibrant, solid color that complements the scene, emphasizing the joyful and celebratory mood. The overall composition should convey a sense of pride and happiness, with the characters standing confidently on or near the staircase, their expressions full of excitement
