Frequently asked questions
- How do I change a specific color in an image?
- Select the source color using the eyedropper or enter a hex code, set your replacement color, and adjust tolerance to control how many similar shades are affected. Preview shows the result before saving.
- What does the tolerance setting do?
- Tolerance controls how closely a pixel must match the source color to be replaced. Low tolerance replaces only exact matches. Higher tolerance replaces a wider range of similar shades.
- Can I invert the colors of an image?
- Yes. Use the invert mode to swap every color with its opposite (white becomes black, red becomes cyan, etc.). This is useful for creating dark mode versions of diagrams and line art.
