Smart Replace (Script for Aseprite)

Smart Replace is a powerful Aseprite extension that replaces colors intelligently—not just with a flat swap, but by preserving the pixel's relative distance from the source color. This means smoother blending, better gradients, and more natural-looking transitions.

• Replace a selected color within a perceptual tolerance

• Fine-tune results using a blend percentage slider

• Works on the entire canvas or just the selected region

• Supports transparency-aware blending

• Built with simplicity and pixel-art precision in mind

• Retouch and recolor shaded artwork without flattening your image

• Create alternate palettes or skins while preserving lighting

• Adjust alpha/transparency shifts in game assets subtly
