Karl is standing on a chair in front of a window, a curious expression as he looks up at something off-screen. His blonde hair is short and spiky, and he’s wearing a bright red shirt and black pants. To color this scene, I would choose a cheery sky blue for the sky outside the window, with a bright yellow sun peeking through. To bring out the bright colors of Karl’s shirt, use a deep red for the backdrop. To contrast the red and black, accentuate the window with a pale turquoise. To bring the image to life and make Karl look more animated, use light brown for his skin and a soft, muted pink for his cheeks.
