PNG 颜色替换器

Color Matching: The tool uses RGB color space to calculate the distance between colors and applies replacement based on your tolerance setting.

Tolerance: Lower values match colors more exactly, while higher values allow for more variation in the source color.

Color Picker: Click the "Pick Color" button and then click on any color in your image to select it as the source color.

Transparency: PNG transparency is preserved during color replacement, so transparent areas remain transparent.
