Replacing Colors Programmatically
Write a script that reads each SVG file's text content, finds fill and stroke color values via regex or an XML parser, and replaces them with new target colors before saving the updated files.
- Use regex or an XML/SVG parser to find fill/stroke attributes
- Map old color values to new target colors in a lookup table
- Save updated files to a new output folder to preserve originals
Handling Colors in Different Formats
SVG colors can appear as hex, rgb(), named colors, or within style attributes and CSS — a robust batch recolor script needs to handle all these formats to catch every color reference in your icon set.
- Check for colors in fill/stroke attributes and style='' blocks
- Normalize named colors (e.g. 'black') to hex before replacing
- Test on a few sample files before running across your full library
Frequently Asked Questions
Will batch recoloring affect gradients inside the SVG?
Gradient stop colors are defined separately within <stop> elements, so your batch script needs to target those specifically in addition to direct fill/stroke attributes.
What's the safest way to test a batch recolor script?
Run it against a small sample subset first and visually verify the output before applying it across your entire icon library, to catch any edge cases in color format handling.
