Making specific text stand out in a PDF often requires changing the highlight color in Adobe Reader. Knowing how to change highlight color in Adobe Reader can transform a dull document into a visually organized study guide or work file. This guide walks you through every step, from basic settings to advanced tricks, so you can customize your highlights exactly how you want.
Adobe Reader is a free tool millions use to view and annotate PDFs. While its default yellow highlight works fine, you might want a different color for different topics. Maybe you use green for key points, blue for definitions, or red for corrections. Whatever your need, the process is simpler than you think.
Why Change The Highlight Color In Adobe Reader
Color coding your highlights helps you find information faster. When you scan a PDF later, your brain recognizes colors and associates them with specific meanings. This is especially useful for students, researchers, and professionals who deal with large documents.
Another reason is accessibility. Some people find yellow hard to read against white backgrounds. Changing to a darker or softer shade can reduce eye strain. Plus, it just makes your PDF look more organized and personal.
How To Change Highlight Color In Adobe Reader (Step By Step)
This section covers the main method for changing the highlight color. Follow these steps exactly, and you’ll be highlighting in your chosen color within minutes.
Step 1: Open Your PDF And Select The Highlight Tool
First, open Adobe Reader and load the PDF you want to work with. Look for the “Comment” toolbar on the right side of the screen. If you don’t see it, click “Tools” at the top, then select “Comment” to open the toolbar.
Click the highlight icon (it looks like a marker pen with “ab” next to it). Your cursor will change to a crosshair. Now you are ready to highlight text, but first, you need to set the color.
Step 2: Access The Color Properties
With the highlight tool selected, look at the top toolbar. You should see a small color swatch icon, usually showing yellow by default. Click on that swatch. A color palette will drop down with several preset colors.
If you want one of these preset colors, just click it. The highlight tool will now use that color. But if you want a custom color, click “More Colors” at the bottom of the palette.
Step 3: Choose A Custom Color
When you click “More Colors,” a window opens with two tabs: “Swatches” and “Color Picker.” The Swatches tab shows a grid of common colors. The Color Picker tab lets you create any color by adjusting RGB (Red, Green, Blue) values or using a color wheel.
For a precise match, use the Color Picker. Enter specific RGB numbers or drag the sliders. Once you find your color, click “Add to Swatches” if you want to save it, then click “OK.”
Step 4: Start Highlighting
Now that you’ve set your color, simply click and drag over the text you want to highlight. The text will appear in your chosen color. You can continue highlighting with this color until you change it again.
Remember, this color setting applies to all new highlights you make. It does not change the color of highlights you already created. To change existing highlights, see the next section.
How To Change Highlight Color In Adobe Reader For Existing Highlights
What if you already highlighted some text and want to change its color? No problem. Adobe Reader lets you modify existing highlights easily.
Method 1: Right-Click And Change
Locate the highlight you want to change. Right-click directly on the highlighted text. A context menu appears. Hover over “Properties” (or “Properties…” depending on your version). A small window opens.
In the Properties window, find the “Appearance” tab. You’ll see a “Color” option. Click the color swatch and pick a new color from the palette or choose “More Colors” for custom options. Click “OK” to apply the change.
Method 2: Use The Comments Panel
Open the Comments panel by clicking the speech bubble icon on the right side of the screen. This panel lists all annotations in your PDF, including highlights. Find the highlight you want to change in the list. Right-click it and select “Properties.” Change the color as described above.
This method is useful if you have many highlights and want to change them in bulk. You can also use the Comments panel to filter highlights by color or type.
How To Change Highlight Color In Adobe Reader On Mac
The steps for Mac users are almost identical to Windows. The interface looks the same, but some keyboard shortcuts differ. Here’s a quick recap for Mac:
- Open Adobe Reader and load your PDF.
- Click the “Comment” tool on the right.
- Select the highlight tool.
- Click the color swatch in the top toolbar.
- Choose a preset color or click “More Colors” for custom.
- Start highlighting.
For existing highlights, right-click (or Control-click) on the highlight and select “Properties.” Change the color from the Appearance tab. The process is identical to Windows.
How To Change Highlight Color In Adobe Reader Using Keyboard Shortcuts
Keyboard shortcuts can speed up your workflow. While there is no direct shortcut to change the highlight color, you can quickly access the highlight tool and properties.
Press “Ctrl + E” (Windows) or “Cmd + E” (Mac) to open the Properties toolbar. This toolbar shows the color swatch for the currently selected tool. You can change the color here without opening the full Comment toolbar.
Another tip: If you have a highlight selected, pressing “Ctrl + I” (Windows) or “Cmd + I” (Mac) opens the Properties window directly. This saves a few clicks.
How To Change Highlight Color In Adobe Reader For Multiple Highlights At Once
Changing multiple highlights one by one is tedious. Fortunately, there is a way to change all highlights of the same color at once.
Using The Comments List
Open the Comments panel. Click the “Filter” icon (funnel shape) at the top of the panel. Choose “Color” from the filter options. Select the color you want to target. The list will show only highlights of that color.
Now, select all these highlights by clicking the first one, holding “Shift,” and clicking the last one. Right-click any selected highlight and choose “Properties.” Change the color, and all selected highlights will update simultaneously.
Using The Find Tool (Advanced)
For very large documents, you can use the “Find” tool to locate all highlights. Press “Ctrl + F” (Windows) or “Cmd + F” (Mac). In the search box, type “highlight” (without quotes). Adobe Reader will find all highlight annotations. You can then select them from the results and change their properties.
This method is less intuitive but works well for power users.
How To Change Highlight Color In Adobe Reader To A Specific RGB Value
Sometimes you need an exact color for branding or consistency. Adobe Reader supports custom RGB values. Here’s how to use them:
- Select the highlight tool or right-click an existing highlight.
- Open the color properties (click the color swatch, then “More Colors”).
- Go to the “Color Picker” tab.
- Enter the Red, Green, and Blue values (each between 0 and 255).
- Click “Add to Swatches” to save it for future use.
- Click “OK.”
Now you can use this exact color for all your highlights. This is perfect for matching company colors or personal preferences.
How To Change Highlight Color In Adobe Reader Without The Comment Toolbar
Some users prefer a minimalist interface. You can still change highlight colors without the Comment toolbar open.
Simply select the text you want to highlight. Right-click the selected text. From the context menu, choose “Highlight Text.” This applies the default yellow highlight. To change the color, right-click the highlight again and select “Properties.” Change the color from there.
This method is slower but works if you have the toolbar hidden. You can also use the keyboard shortcut “Ctrl + H” (Windows) or “Cmd + H” (Mac) to apply the default highlight quickly.
How To Change Highlight Color In Adobe Reader For Different Document Types
Adobe Reader works with many PDF types, including scanned documents, forms, and protected files. The highlight color change process is the same for most, but there are exceptions.
Scanned Documents
Scanned PDFs are images of text. You cannot highlight them directly unless the PDF has been OCR (Optical Character Recognition) processed. If your scanned PDF is not OCR, you cannot change highlight colors because there is no selectable text.
To highlight a scanned PDF, you need to use the “Drawing Markups” tool (like the rectangle or freehand highlight). These tools have their own color settings, which you can change similarly.
Protected Or Encrypted PDFs
Some PDFs have restrictions that prevent editing or commenting. If you cannot highlight at all, the document is likely protected. You will need the password to remove restrictions. Once removed, you can change highlight colors normally.
How To Change Highlight Color In Adobe Reader On Mobile
Adobe Reader is also available on iOS and Android. The mobile app has a similar interface but with some differences.
On IPhone Or IPad
Open the PDF in Adobe Reader. Tap the “Comment” icon (speech bubble) at the top. Select the highlight tool from the toolbar. Tap the color swatch at the bottom of the screen. Choose a preset color or tap the “+” icon for custom colors. Start highlighting.
On Android
The process is nearly identical. Open the PDF, tap the “Comment” icon, select the highlight tool, and tap the color swatch. Choose your color and highlight away.
For existing highlights on mobile, tap the highlight to select it. A toolbar appears with a color option. Tap it to change the color.
How To Change Highlight Color In Adobe Reader: Troubleshooting
Sometimes the color change doesn’t work as expected. Here are common issues and fixes.
Color Not Changing
If you change the color but the highlight remains yellow, you might have selected the wrong tool. Make sure the highlight tool is active, not the “Sticky Note” or “Text Box” tool. Also, check if you are changing the color of an existing highlight or the default tool color.
Color Resets To Yellow
Adobe Reader resets the highlight color to yellow when you close and reopen the program. This is by design. To avoid this, you can create a custom tool preset (see next section).
Cannot Find Color Option
If the color swatch is missing, your toolbar might be collapsed. Click the “>>” arrow at the end of the toolbar to expand it. If still missing, reset the toolbar by going to “View” > “Show/Hide” > “Toolbars” > “Reset Toolbars.”
How To Change Highlight Color In Adobe Reader: Advanced Tips
For power users, here are some advanced techniques to make highlighting even more efficient.
Create A Custom Tool Preset
You can save your favorite highlight color as a custom tool. Right-click the highlight tool icon in the toolbar. Choose “Add to Quick Tools” or “Customize Quick Tools.” Then, set the color and other properties. This preset will stay even after restarting Adobe Reader.
Use Multiple Highlight Colors Simultaneously
Adobe Reader does not allow multiple highlight colors active at once by default. However, you can switch colors quickly by using the “Properties” toolbar (Ctrl+E). Keep it open and change colors with a single click.
Export Highlights With Color
When you export comments from a PDF (File > Export To > Comments), the highlight colors are preserved in the exported file. This is useful for sharing annotated PDFs with others.
