Avoid using bright, cheerful colors like pastels or vibrant yellows, exclude any scenes that depict sunlight, clear skies, or daytime settings, do not include any characters or figures with happy or smiling expressions, avoid incorporating everyday objects or mundane surroundings that would detract from the ghostly atmosphere, stay away from lush, thriving landscapes or colorful gardens, exclude playful or friendly animals, and do not feature innocent or happy children in the image, as these details may contrast with the scary theme you want to convey.
