Barbie is showing her skill with her blue sword in a classic fencing pose. Her dress is a beautiful shade of blue with a white shirt and gold belt. Her hair is held back securely with a delicate blue ribbon. To create a sharp contrast and to show off her features, I would color her in bold purples and violets. To add a touch of sparkle, I would fill her gold belt with golden accents. For the sword, warm silver tones and deep blues can be used to create a sense of movement. To add to the overall atmosphere, you can use bright yellow and orange hues to create a sun-filled backdrop.
