Whether you want to change clothing colors, add accessories like a different hat, or alter their expression, the AI handles the pixel-perfect adjustments for you. This approach makes sprite editing faster and more accessible, allowing you to focus on your creative ideas instead of tedious pixel-by-pixel changes. It’s perfect for quick experiments or detailed modifications.
