In this coloring page, Barbie is looking glamorous in her white dress with a pretty pink sash and matching bow in her hair. She has a pink purse in one hand and a pink bracelet around her wrist. Barbie is admiring her reflection in the mirror behind her, and both versions of her have the same elegant look. To complete this image, I would begin by adding bold shades of pink to Barbie's outfit and purse. The bracelet should get accents of silver to stand out and bring texture. The mirror can be filled with a cool blue accent with hints of white along the edges. Finally, fill out the environment with light gray tones for a classic and elegant look.
