Frequently Asked Questions

Why would I need a green ink signature?expand_more
In India, green ink is traditionally reserved for gazetted officers and certain notarial stamps. Some government documents and academic certifications require green ink to indicate authority or official endorsement.
Will the green look natural?expand_more
Yes. The tool maps the ink intensity from your original signature to green shades, so dark strokes become deep green and lighter strokes become lighter green - just like writing with a real green pen.
Can I convert from blue ink to green?expand_more
Yes. The tool first calculates the grayscale intensity of each pixel, then maps it to the green colour spectrum. It works regardless of the original ink colour.
What shade of green is used?expand_more
The default target is a professional dark green (#15803d). You can adjust the slider to make it lighter or deeper depending on your requirement.
