This picture depicts Cinderella as a lackey. She is wearing a dress made of rags, and a tiny mouse can be seen perched atop her head. Her expression shows a faint hint of despair, as if she's given up hope that things ever getting better. To color this page, I would suggest using muted, dusty tones, to capture the undertone of sadness in the image. Shades of blue and purple, alongside grays and blacks, would do a great job of conveying Cinderella’s suffering. Pops of color can be added as accents, as when you want to draw attention to the bright eyes of the mouse, or the beauty of Cinderella’s dress despite its humble materials. These accents should be used sparingly, however, to emphasize the weariness of the scene.
