How to Add and Customize Colors in Acrobat PDF Comments
Product
Adobe Acrobat
Device & OS
not provided
Scenario
Adding drawings or annotations to a PDF and needing to select specific or custom colors that are not available in the default quick palette.
Observed behavior
The available color controls and custom options vary or appear missing depending on the operating system and the specific version of Acrobat being used.
Before you start

Ensure you know which version of Adobe Acrobat you are running, as the annotation properties dialog and system color pickers behave differently on Windows compared to macOS.

Solution 1Recommended

Modify Annotation Color via Properties Menu

Access the properties of your drawing annotation to manually change its color and adjust opacity.

The most direct way to access advanced color options for any PDF comment or drawing is through its dedicated Properties menu, which pulls up the full color settings supported by your current operating system.

1
Select the annotation

Open your document and click directly on the existing drawing or comment annotation to highlight it.

2
Open Properties

Right-click the selected annotation and choose 'Properties' from the context menu.

3
Choose a custom color

In the Properties dialog box, click on the color square. If your OS supports it, select the 'Custom Color' or 'More Colors' option to input a specific HEX or RGB color code.

4
Adjust opacity

Use the opacity slider in the same window to make your annotation semi-transparent or fully solid, then click 'OK' to save your changes.

Modify Annotation Color via Properties Menu
Default Properties: If you want to use this custom color for future drawings, check the 'Make Properties Default' box at the bottom of the Properties dialog before clicking OK.

Frequently Asked Questions

Why can't I find custom colors in Acrobat's Mac version?

The Mac version of Acrobat utilizes the macOS native color picker. When you click the color box in Acrobat's properties, it opens the Mac color wheel window. You may need to click 'Show Colors' or look for the separate window to input custom hex codes.

Does changing the annotation color affect the original text in the PDF?

No, annotations, drawings, and comments act as an overlay on top of your PDF document. Changing their color or adjusting their opacity will not alter the original text or images underneath them.

Can I set a custom color as the default for all future PDF comments?

Yes. After you change the color in the annotation's Properties menu, check the box labeled 'Make Properties Default' before closing the window. Any future annotations of that specific tool type will automatically use your new custom color.
