Acrobat offers several ways to modify the appearance of the redaction marks by using custom colors, text, and specific codes. There aren’t any government regulations regarding the color or text used in a redaction mark. The ability to customize how redaction marks appear means you can use an in-house color scheme to represent the types of material redacted, such as instances of different names redacted in different colors.
Before selecting text for redaction, follow these steps to customize the redaction marks:

Figure 3: Choose custom colors and text instead of the default black blocks for redacting.

Figure 4: Use a combination of color and text as redaction marks.
Often, you may need to read through many documents looking for the same content to redact. Acrobat 8 Professional offers an efficient way to handle that task.
