How Color Masking Works
Color masking is a simple but effective method that makes text invisible by setting its color to match the background exactly. This technique:
- Uses CSS color properties to match text and background colors
- Works in any environment that supports HTML/CSS styling
- Can be revealed by selecting/highlighting the text
- Maintains the original text structure and formatting
The text remains in the document and can be copied, but appears invisible until selected or the background color changes.

Frequently Asked Questions
Why can people still see my text when they select it?
This is a natural limitation of color masking - when text is selected, most browsers and applications will highlight it with a different background color, making it visible. If you need text that remains hidden even when selected, consider using our zero-width character method instead.
Will this work in my email?
Color masking works in HTML emails that support CSS styling. However, some email clients may strip or modify CSS styles, so it's best to test with your specific email platform first.
Can I use this in a Word document?
While Microsoft Word and similar document editors support text colors, the behavior might be different from web browsers. The text may become visible when printed or exported to different formats.
How do I make sure the colors match exactly?
Our tool automatically ensures exact color matching. If you're implementing manually, make sure to use the exact same color values for both text and background (e.g., same hex code, RGB values, or color name).
