Frequently Asked Questions
Why would I need a red ink signature?expand_more
Red ink signatures are commonly used for corrections and markup on official documents, teacher/examiner review marks, audit approval stamps, and certain legal endorsements that distinguish signer roles.
Will the red look natural?expand_more
Yes. The tool maps your original ink intensity to red shades, preserving stroke thickness and detail. Dark strokes become deep red, lighter strokes become lighter red.
What shade of red is used?expand_more
The default target is a professional crimson red (#b91c1c). You can adjust the slider to make it lighter (pink-red) or deeper (dark crimson).
Can I convert a blue signature to red?expand_more
Yes. The tool first extracts the grayscale intensity from your signature, then maps it to the red colour spectrum. It works with any original ink colour.

Common Mistakes to Avoid
Low-contrast scan: If your original signature is faint or washed out, the red version will also appear faint. Use a dark, clean scan for best results.
Colored background: The tool works best on white or light backgrounds. A colored background may interfere with the color conversion.
